DataPrism

DataPrism is a TypeScript SDK that overlays existing object storage, encrypting files client-side before upload, splitting them into fragments dispersed across independent providers, and anchoring a constant-size integrity fingerprint on a public registry. It addresses the exposure that provider-held encryption keys, single-address ciphertext copies, and unverifiable key custody leave in place, while keeping existing storage accounts, regions, and contracts unchanged.

The pipeline handles encryption, fragmentation, redundancy across a configurable number of destinations, and content-addressed integrity checks, with reconstruction performed client-side. Destinations include AWS, GCP, Azure, on-premise storage, and anything speaking the S3 API, configurable without a second integration. The SDK runs in the browser or on a server, and a sealed index on the public registry supports third-party verification without exposing content.

DataPrism is aimed at enterprises holding regulated or sensitive data, including teams working on cross-border transfer compliance and blind ingestion. Pricing is a single annual subscription scoped to what is protected, with customers keeping their own storage rates. A design partner program is open by application, offering a limited number of places for one real use case over the program's duration.
