DeveloperWeek 2020

In this session, we will present a paper on tamper-proof logging work done at Equinix to support our SaaS initiatives. The work is based on using blockchain technologies to effectively and securely deliver logging services and also support logging needs of SaaS services.

A case for tamper-proof login is a requirement in many areas in financial institution and new emerging multi-cloud SAAS area.

An example of such a case is a dispute between a bank and a customer about a transaction. On one hand, the bank can’t just present the whole log as evidence, as the log contains also information about transactions of other customers. On the other hand, the customer involved in the dispute (or more likely a technical expert working on their behalf) should have a chance to verify the integrity of the records relevant to the dispute.

Similar concerns also arise in the context of multi-tenant cloud environment there can be requirement that data should be shared between different entities in a context and logs events which are generated needs stored and presented in a for tamper proofing to a regulator of a different entity. This means the integrity of log can be verified by the owner, no other logs can be added. The integrity of any record can be proven to a third party without exposing the PII(Personally Identifiable Information ). The must also has the extraction process is efficient in both time and space. The verification process should be efficient in time
