Here you find the details for the internship named "Use blockchain to timestamp proof documents stored in Activescale" in the company Western Digital.

Name: Use blockchain to timestamp proof documents stored in Activescale
Company: Western Digital

In some industries it is required to be able to proof that a certain document (or a version of it) existed at a specific moment in time and has not been modified since then. If the number of documents is relatively low this can be solved by registering documents with a government institution (e.g., patent bureau), a notary, etc. But this is not scalable and potentially costly. Blockchain technology allows to make this proof publicly verifiable without the need of a middleman.

Possible use cases:
- Document timestamping;
- Guarantee data integrity and proof provenance
- Regulatory compliance (SEC 17a-4, Sarbanes-Oxley, HIPAA,…). offers an API to hash documents, timestamp proof the hash and anchor it to a blockchain. This needs to be integrated with ActiveScale to process newly written documents with the chainpoint API and attach the received proof to the documents.

The following tasks are proposed:
- Investigate chainpoint API’s and ActiveScale API’s
- Describe in detail the complete data flow:
o New object written
o Hashed, time proofed, anchored in blockchain
o Associate proof with document
o Third-party verification process
- Develop a working prototype
