We are living in an age of “data feudalism.” Big data as a new asset class worth trillions of dollars has been created by us—individuals and organizations—but nearly all of the value is expropriated by the new digital landlords.

Business-to-businessdatawillbehuge,too.Manylargecorporationshavestronggovernancemechanismsfortheirhardassets.However,accordingtoDr.ElizabethM.Pierce,aprogramchairfortheInternationalConferenceonInformationQualityhostedbyMITin2015,
Information assets are often the worst governed, least understood, and most poorly utilized key asset in most firms because [information] is increasingly easy to collect and digitize, has increasing importance in products and services, is very difficult to price, has a decreasing half-life, has increasing security and privacy risk exposure, and is a significant expense in most enterprises.3

Privacy is the foundation of freedom. While digital conglomerates create great value for consumers by mining consumer data, they undermine our traditional concepts of privacy and the autonomy of the individual.

For many businesses, the likely path to creating competitive advantage is by subjecting big data to advanced analytics. Big data has become a corporate standard, and data analytics is a prerequisite to remain competitive.

Security of consumer and business data remains a big issue. Any organization can be hacked.

The more data are linked, shared, or sold to third parties, the more consumer privacy is violated. The trend toward restoring data ownership to consumers will require organizations to rethink their approach to big data.

As the number of IoT devices expands, so will the number of transactions. Keeping up with these transactions increases computational requirements, which can become a serious challenge.

Telstra’s use of blockchain technology will provide peace of mind to consumers who will know that their data are safe and that they have control over who has access to their information.
Traditional data sharing systems generally enable reverse-engineering the data to obtain any missing information. Blockchain enables organizations to segment data, store each segment into a vault, and maintain full control over who has access to those vaults, governed by asymmetric cryptography and smart contracts.

The importance of governance: Quality and compliance
Datagovernanceisinvolvedwithcreatingguidelinesandstandardstoachievedataqualitymanagementandensuringcompliancewiththeprocessesdevelopedarounddatausage.50Masterdatamanagement,anaspectofdatagovernance,isgrowinginimportancetoensuredataquality,becausedecadesofusingandstoringdataindisparatestoresandformatshasresultedinmanyinconsistencies,makingitdifficultforcompaniestounderstandtheirdata.51Impropermasterdatamanagementprocessescouldresultinavarietyofproblemsthatcouldharmthebusiness,suchasoperationalproblemsorincorrectcustomerdata.Assuch,duetotheincreasingamountofdataavailable,masterdatamanagementisincreasinglyimportanttoorganizations.52
Intheory,masterdatamanagementwillbecomemoreimportantsinceblockchainpreservesdataindefinitely.Resilienceandirreversibilityaretwokeyattributesofblockchains;oncetransactiondataareaddedandacceptedbythenodes,theybecomeimmutable.53However,blockchaindoesnotmagicallytransformlow-qualitydataintohigh-qualitydataintermsofconsistencyandcorrectness.Garbageinstillmeansgarbageout.Ifbadorlow-qualitydataarepresentedintherightway,theywillbeappendedtotheblockchain.Ifadocumentcontainsfalseinformationbutispresentedintherightway,itwillstillenduponablockchain.54 Thereforeorganizationsrequireadata-governanceframeworkthatcombinesbusinessandtechnicalperspectivesrelatedtodataqualitytorespondtostrategicandoperationalchallengesinvolvedwithdatathatisaddedtoablockchain.55
Blockchain does not magically transform low-quality data into high-quality data in terms of consistency and correctness. Garbage in still means garbage out.
Data governance has become such a necessity that organizations can no longer expend minimal effort to steward their data.

Whenever an entity interacts with data, the system will add an entry to the ledger. The entry will indicate which piece of data was used and why. Any access and changes made to the individual’s data will be immediately visible. In effect, the system enables a verifiable data audit.

Sesame Credit is a credit rating system that incorporates social scoring. It uses big-data insights to assign a social score based not only on a person’s dealings with businesses, but also on how he or she interacts socially online. Individuals could be rewarded or penalized for their behavior. It will help China to scale its social credit system to a national level.
