Abstract
A record storage system maintains an interdependent series of hash values for records submitted to the record storage service by one or more clients. The record storage service generates a hash value for each record based at least in part on the content of the record and a hash value of one or more previous records. In some examples, the generated hash values are saved in an audit database by the clients. Clients may retain some, all, or none of the hash values based on the amount of auditing desired and the amount of storage space available in the audit database. The clients are able to verify the integrity of records submitted to the record storage system by retrieving the records from the system, recalculating the hash values of the records, and comparing the recalculated hash values to the hash values retained by the client.
