It then states the core technical change as utilities now having to manage and analyze much more frequent time series data from many more devices. The document proposes that utilities need to provide analytics on this data 1000x faster while adhering to governance standards. It evaluates data structures like B+ trees and log structured merge trees to optimize for the high volume of sequential writes required to store the time series data.
Big Data for Big Power: How smart is the grid if the infrastructure is stupid?OReillyStrata
Introducing the concept of SLEx (Substation Life Extension) and Intelligent Sensing at teh Edge when it comes to Smart Grid activities. This is a novel concept on truly using sensors to extend substation life, and then dealing with the Big Data that has just been introduced by using state of the art sensing technology. Both SLEx and Intelligent Sensing at the Edge are concepts that have been introduced by Brett Sargent who is CTO and VP/GM of Products at an innovative sensor company located in Silicon Valley.
What are big data in the contacts of energy & utilities, and how/where can the utilities find value in the data. In this C-level presentation we discussed the three prime areas: grid operations, smart metering and asset & workforce management. A section on cognitive computing for utilities have been omitted from the presentation due to confidentiality - but I tell you - it is mind-blowing perspectives on how IBM Watson will help utilities plan and optimize their operations in the near future!

This document discusses predictive maintenance using sensor data in utility industries. It describes how sensors can monitor infrastructure and predict failures by analyzing patterns in sensor data using machine learning models. An architecture is proposed that uses big data frameworks like Spark, Kafka and HBase to collect, analyze and store large volumes of real-time sensor data at scale. Predictive analytics on this data with techniques like clustering and regression can detect anomalies and predict failures to enable condition-based maintenance in utilities. Modeling uncertain sensor readings with probabilistic and autoregressive approaches is also discussed.

Blockchain, Hyperledger and the Oracle Blockchain PlatformJuarez Junior
This document discusses blockchain and Hyperledger Fabric. It provides an overview of enterprise blockchain, describes the key components of Hyperledger Fabric including peers, smart contracts, consensus and the ledger, and explains the transaction flow. It also covers blockchain application development and introduces Oracle's Blockchain Platform as a fully-managed blockchain as a service.
This document summarizes a research paper that proposes using blockchain technology for authentication in Hadoop instead of the traditional Kerberos protocol. It describes some security issues with Kerberos, such as single point of failure and replay attacks. The authors created a model for a distributed authentication mechanism using blockchain concepts that is integrated with the HDFS client. Key features of the blockchain authentication method include decentralized authentication without keys, an unalterable record of transactions, zero single points of failure, and prevention of data theft. The implementation uses a private blockchain to store user information that is verified for authentication to access data on HDFS.

3) Security considerations including privacy, access controls, and ensuring determinism and isolation of smart contracts.
HBaseCon 2013: Using Coprocessors to Index Columns in an Elasticsearch Cluster Cloudera, Inc.
This presentation explores the design and challenges HappiestMinds faced while implementing a storage and search infrastructure for a large publisher where books/documents/artifacts related records are stored in Apache HBase. Upon bulk insert of book records into HBase, the Elasticsearch index is built offline using MapReduce code but there are certain use cases where the records need to be re-indexed in Elasticsearch using Region Observer Coprocessors.
HBaseCon 2013: Using Coprocessors to Index Columns in an Elasticsearch Cluster Cloudera, Inc.
This document discusses implementing an HBase coprocessor to index columns from HBase into an Elasticsearch cluster. It describes storing book records from publishers and libraries in HBase and indexing them into Elasticsearch using MapReduce jobs. To handle updates, a coprocessor uses HBase's checkAndPut method to verify the record version before updating and indexing the new version into Elasticsearch, ensuring consistency between the two systems.
Chaincode refers to programs that are run on Hyperledger blockchain networks to manage ledger state and transactions. It handles business logic that is agreed to by network members. Chaincode is isolated from endorsing peers for security and initializes and manages state through submitted transactions.
This document discusses security issues with Hadoop and available solutions. It identifies vulnerabilities in Hadoop including lack of authentication, unsecured data in transit, and unencrypted data at rest. It describes current solutions like Kerberos for authentication, SASL for encrypting data in motion, and encryption zones for encrypting data at rest. However, it notes limitations of encryption zones for processing encrypted data efficiently with MapReduce. It proposes a novel method for large scale encryption that can securely process encrypted data in Hadoop.

CouchBase The Complete NoSql Solution for Big DataDebajani Mohanty
Couchbase is a complete NoSQL database solution for big data. It provides a distributed database that can scale horizontally. Couchbase uses a document-oriented data model and supports the CAP theorem. It sacrifices consistency to achieve high availability and partition tolerance. Couchbase is used by many large companies for applications that involve large, complex datasets with high user volumes and real-time requirements.

Chapter 12
Integrating Non-
Blockchain Apps
with Ethereum
Although you can build entirely blockchain-based applications, it is far more likely that your applications will be a combination of traditional and blockchain components. You learn in Chapter 3 that some use cases lend
themselves well to blockchain apps but others do not. In this book, we chose to
highlight one use case, supply chain, because blockchain offers clear advantages
over traditional methods. However, even a comprehensive supply chain applica-
tion will likely run partially as a traditional application and partially on the
blockchain.
Many emerging blockchain apps consist of core components that operate as smart
contracts and other components that operate as traditional applications that
interact with users and provide supporting functionality. This hybrid approach to
application development requires the capability to integrate the two different
development models. In other words, to develop hybrid applications that run par-
tially on the blockchain, you need to know how to design them to talk with each
other and operate seamlessly.

blockchain and databases

blockchain apps
206 PART 4 Testing and Deploying Ethereum Apps
Distributed application design and development isn’t new. In fact, some of the
difficulties with distributed applications led to the need for technologies like
blockchain. Remember that blockchain technology doesn’t solve all application
problems, but it does have its place. Now that you know how to develop dApps for
the Ethereum blockchain, in this chapter you learn how to integrate your smart
contracts with applications that do not include blockchain technology. The capa-
bility to integrate blockchain and non-blockchain applications makes it possible
to develop applications that use the right technology for a wide range of needs.
Comparing Blockchain and
Database Storage
In Chapter 2, you learn about some of the differences between storing data in a
blockchain and a database. Both technologies can store data, but clear differences
exist between the two. One of the first obstacles you might encounter when asked
to integrate blockchain with an existing application is determining what data you
should migrate to the blockchain.
Traditional applications store most of their data in a database. Databases provide
fast access to shared data. Blockchains can also provide access to shared data, but
they may not be as fast as a database. As you learn in Chapter 2, there are other
differences as well. It is important that you understand the relative strengths of
each data storage technique to make good design decisions for integrating block-

Big Brother Big Sister Bluemix Architecture from #HackathonCLTDave Callaghan
Big Brother and Big Sisters brought their enterprise system challenge to #HackathonCLT. I wanted to design a system that could support 10x the membership with the same expense. By using Bluemix to provide scale, the Watson APIs for both ingestion and analytics, and their Hyperledger implementation for security paired with HBase, I believe we have a potential solution. More to come!
Stormwater analytics with MongoDB and PentahoDave Callaghan
Use MongoDB and Pentaho to rapidly evaluate a use case for the City of Charlotte's Stormwater Management System by creating "A Single View of a Raindrop".
This document discusses implementing a single view of customer data across an enterprise. It begins by outlining common barriers such as a lack of digital experience strategy, silos between teams, and challenges measuring ROI. It then proposes using MongoDB as a flexible data platform to integrate new and existing data sources. Pentaho is recommended for blended analytics across data silos. The approach aims to provide a single customer view, resolve technology skills gaps, and iteratively define strategies by starting small projects and engaging stakeholders.
This document discusses big fast data and perishable insights that must be acted on quickly. It describes streaming analytics as analyzing data in motion from real-time sources to gain opportunities and avoid crises. Examples of use cases provided are real-time market surveillance and an IoT-enabled smart bank that can send targeted offers to customers. Key components discussed are storing high velocity data in HBase and analyzing it using Storm or Spark on Kafka.
Orphans in the Desert is an online platform that aims to help people with rare diseases by allowing them to input unstructured health data to be analyzed by IBM's Watson for potential diagnoses, and to cluster patients together in order to incentivize treatment research. It serves as a safe place for rare disease patients to describe their symptoms freely without bias or preconceptions, and provides educational resources, support groups, and information on clinical studies. The platform allows for both individual analysis of user data as well as macro-level statistical analysis of particular or general rare diseases.
This document discusses modern data, data governance, and the Apache Atlas proposal. It defines modern data as including clickstream, web, social, geo-location, and IoT data that uses a schema-on-read approach, while traditional data refers to ERP, CRM, and SCM data that uses schema-on-write. It also discusses how modern data refers to stream processing using a streaming model, while both modern and traditional data can use batch processing. The document then defines data governance and discusses the Apache Atlas proposal, which allows governance visibility and controls for Hadoop and non-Hadoop data through services like search, lineage, access control, auditing, and lifecycle management powered by a flexible metadata repository.
This document provides a roadmap for implementing big data solutions at telecommunications companies in Colombia. It identifies opportunities in improving customer experience through customer profiling and churn reduction, and in network management through fault isolation. While telecom companies spend more on big data than other industries, they see a lower return due to having less structured data. The document recommends focusing initial efforts on using existing internal customer and network data to drive outcomes in priority business areas like customer retention.
Our data science approach will rely on several data sources. The primary source will be NYPD shooting incident reports, which include details about the shooting, such as the location, time, and victim demographics. We will also incorporate demographics data, weather data, and socioeconomic data to gain a more comprehensive understanding of the factors that may contribute to shooting incident fatality. for more details visit: https://bostoninstituteofanalytics.org/data-science-and-artificial-intelligence/
Biopesticides for insect control in AgricultureSouravBala4
Biopesticides are derived from natural materials like animals, plants, bacteria, and certain minerals. They are used to control pests through non-toxic mechanisms, making them an environmentally friendly alternative to conventional chemical pesticides. Biopesticides are often highly specific to their target pests, reducing the risk of harming beneficial organisms and minimizing environmental impact. They play a crucial role in integrated pest management (IPM) strategies, helping to promote sustainable agricultural practices.

2. Introduction
● This project started during the Blockchain in Healthcare Code-A-Thon in Washington DC for the
2017 Blockchain in Healthcare Summit.
● Overall, the goal was to develop a solution that enhances interoperability and demonstrates the
potential to seamlessly incorporate blockchain technology into existing HealthIT systems.
●
Specifically, I took the Metadata Tagging and Policy Expression track, to demonstrate the use of of
blockchain for security metadata and tagging to manage access, provide auditing and provenance
information.
●
I took my lead from the Blockchain For Health Data and Its Potential Use in Health IT and Health
Care Related Research paper,
Our proposal involves the use of a public blockchain as an access-control manager to health records that are
stored off blockchain.
….
There are currently no open standards or implementations of blockchain that utilize this approach but
research supports the feasibility of the proposed solution.
● My goal was to provide an implementation that could be used by corporate IT departments in the
Health space with an eye to Innovation Risk Management.
– Don’t change more than you absolutely must
– New technologies fail in the enterprise because of Governance standards issues rather than technical issues
– Don’t let the perfect be the enemy of the good
3. Current Architecture
● According to the Blockchain for HealthcareIT paper, any blockchain for
health care would
– Need to be public
– need to include technological solutions for three key elements:
● Scalability
● Access security
●
Data privacy
● According to the MIT paper on decentralizing privacy, the off-blockchain
storage needed for scalability should be on a similar data store
following the Kademlia specification for a distributed hash table (DHT).
● The overall architecture would look similar to the diagram on the
following page with services as a proxy for corporate health IT
departments and a public blockchain and, presumably, DHT.
5. Perspective
● Private blockchains are technically far inferior to public blockchain implementation. If it was
only a technical discussion, we would be able to move on. But technical will always take a
backseat to the perception of regulatory requirement. Best to take a page from Supply
Chain Management and EDI and make the specification, not the implementation, public.
– Prefer publicly available standards to publicly available systems.
● Try not to introduce a new technology to an IT departments with a new programming
language. R3 spent $53M to produce a framework in Kotlin. Solidity, Ethereum?
● Regulated IT departments distrust external data the way mice distrust tigers. They will
launch a POC, but it’ll stay a science project.
6. Proposal
● We’ve never had a data revolution and we’re not getting one now.
– When we needed more flexible data models, we added relational database
in addition to mainframes.
– When we needed to aggregate enterprise data, we added data warehouses.
– When we needed to store internet-scale data, we added Hadoop clusters.
– When we needed to react to device-scale data in real-time, we added Spark.
– Now we need to manage trust externally at scale.
● How do we make this merely additive?
8. Blockchain Model for Healthcare
● I am going to suggest a blueprint that hopefully follows the path of least resistance through your
enterprise data governance stage gates.
● I am going to make a few datacenter assumptions:
– There is an onsite Hadoop data lake
– The data lake is secured
●
Authentication – Apache Knox
●
Authorization – Apache Ranger
●
Audit – Apache Ranger
●
Data Protection – Apache Ranger KMS
– You have the tools in place for a standard Lambda architecture (Hbase for speed, HDFS for batch, Hive/Impala for
reporting). Hbase 0.98+ is really the only mandatory component, though.
– There is an ability to consume and serve public RESTful APIs, but they have to go through a some sort of
integration layer
●
We will be building the chaincode using IBM’s Hyperledger Fabric, so hopefully your organization
– allows Apache-licensed open-source apps
– primarily codes in JVM languages (Java, Scala)
– having an open mind to Google’s Go is a really, really nice to have.

11. Application Layer
● At the API level, the MIT Enigma project provides the guidance we need to build our APIs.
– Note that in all of these examples, it is assumed that the user has previously created a profile in the company’s existing identity
and access management system.
● A user installs an application to access their EHR from the provider’s system.
● When the user signs up, a new compound identity (user, company) is created and sent, with predefined
permissions, to the blockchain.
● Data sent from the user to the system is encrypted using this compound identity.
● Permissions can be set at any time by the user, limited by certain corporate rules (no one is allowed to request
that PHI be made public, for example.)
● Services that request permission to query data, for research purposes for example, also create a compound
identity.
● Requests for data return some anonymized subset of data. The principal of least exposure will be adhered to
based on the corporate governance strategy and the user’s preference. Any exposed data must be agreed to be
exposed by both the company and the user.
● Note that a compound key is created, just like the Enigma model where a public blockchain is used. While
technically this would not be necessary in a private blockchain, this is meant to be consumed by another company
with their own private blockchain, or even a consortium with a public blockchain. Regardless, we are implementing
locally but planning to distribute globally.
12. Interface Layer
●
Data that is sent from a device to the system is stored on Kafka.
●
A Spark job will pull the data from the Kafka topic, create a key for Hbase, and then store the
data in both Hbase and Blockchain.
●
HBase is going to rely on cell-based tags to enforce the terms of the blockchain contract by
providing role-based visibility at the datum level. This is the injection part of of trust injection.
●
When a record is first created in Hbase through this system, this record will be persisted but not
yet visible. Hbase is extremely fast while blockchain is extremely slow. However, the assumption
will be that eventual trust will be sufficient for most use cases. This is an asynchronous system
with a fairly hefty latency.
●
Periodically, through some scheduler like Oozie, the blockchain will be queried to retrieve
records that have been authenticated but not yet minimized. Those records will compare a have
of their content against a hash of the Hbase content using the rowkey as a match. When there is
a match, the cell-level visibulity will be updated in Hbase and the blockchain will just store a
pointer to the Hbase record, rather than the full dataset.
13. Implementation
● Hbase is a sparse, distributed, persistent multidimensional sorted map, which is indexed by a row key,
column key, and a timestamp. Row keys are unique. Cells store data as key value pairs and are stored
in a column family.
● Every cell can have zero or more tags. Every tag has a type and the actual tag byte array. Just as row
keys, column families, qualifiers and values can be encoded , tags can also be encoded as well. You can
enable or disable tag encoding at the level of the column family, and it is enabled by default.
● Hbase provides two levels of cell level access control
– Cell level ACL
● Sets RW using Role-based Access Control (RBAC)
– Cell Level Visibility
● Allows labels to be associated with the data cells. Cells across rows and columns can have visibility
labels. Users or groups can be granted authorization to the labels.
● For example, certain cells can have a visibility label called ‘private’. Only users granted
authorization to ‘private’ can access the labeled data.
● Another example, patient or customer data can be labeled ‘branch1′, branch2’ etc based on where
the patient or customer is located or registered. A doctor or administrator can only access the data
that he or she is authorized.
14. Implementation
● Interpreting the labels authenticated for a given get/scan request is a pluggable algorithm.
By creating an algorith, it will be possible to add metadata management to this process,
using an existing corporate metadata repository, a tool such as Cloudera navigator, or even
storing the metadata in a column family on the same Hbase row.
● The ID of the blockchain serves as a pointer to the Hbase record. Access to Hbase is not
done through the blockchain, so its necessary to reflect blockchain rules at this level.
● Apache Ranger is used to manage role-based and tag based solutions and can also store
and operate on metadata. At this time, only Hive and HDFS can have their access and
auditing needs handled by Ranger. This functionality will need to be provided in order to
enable this level of security out of the box.
15. Summary
● The tools to implement blockchain are, to some extent, already available
in most Health Care enterprises.
● While a network of loosely connected private blockchains
communicating though a RESTful APIs conforming to a public
specification is not ideal from a technical perspective, it is more likely to
be implemented into an existing IT infrastructure.
● The goal of having the patient being involved in their own EHR is
preserved though the implementation of IBM’s Hyperledger Fabric using
MIT’s specifications.
● Hbase can be used as the off-blockchain storage. While it is not as
seamless as storing to another distributed hash tag, it does provide the
ability to store and manage metadata and providence at the cell level.
