Q: Compare CAStor's Content Integrity Seal to the
state-of-the-art in content integrity.

A: Most CAS products make use of hashing algorithms hardwired into the storage software to compute the identifying 'tags' for the stored information. The most common algorithms (MD5, SHA-1) have already been successfully attacked in academic demonstrations, illustrating increasing vulnerability to forging and compromising any guarantees of data integrity. As these hashes are 'hardwired' into the system, the identifying tags and the integrity seals are one and the same and together go stale over time. The hundreds of Petabytes thus stored to date will unavoidably share that same fate.

Avoiding the pitfalls of hard coded hashing algorithms, Caringo's 'hot-swappable,' upgradeable hashing architecture uses split tags and seals, together in an open, customer-auditable data structure. With this patent pending process, Caringo is the first to deliver a storage product able to guarantee uncompromised, very long term integrity with no downside.
