Asserting claims: Cryptographically signing the digital artifacts we produce

Why is SFO Museum signing the vector embeddings that we’re producing? To provide an additional guarantee that the data we are publishing is, in fact, the data we published. Vector embeddings are, by their nature, basically impossible to “spot check”. Their size, shape and volume lend themselves to subtle, often imperceptible, corruption whether those changes are introduced by malice or negligence. By providing digital signatures for these embeddings we can provide the means to ensure that the data have not been tampered with after they’ve been downloaded from our website.
