Enhanced encryption for face-related data

A set of non-transitory, machine-readable media storing instructions that, when executed by a set of processors, causes the set of processors to perform operations comprising:

• obtaining an encrypted search vector, wherein:
• the encrypted search vector is determined based on a first image and a target encryption key, and
• the target encryption key is associated with an organization identifier based on a parameter associated with the organization identifier stored in a record;
• obtaining a first encrypted vector by searching an-a first encrypted vector set stored in a first database based on the encrypted search vector, wherein:
• for each respective encrypted vector of the first encrypted vector set, the respective encrypted vector is generated by encrypting a respective vector using the target encryption key,
• a second encrypted vector set is stored in a second database,
• a second encrypted vector of the second encrypted vector set is encrypted without using the target encryption key, and
• obtaining the first encrypted vector comprises selecting the first database for a search operation;
• and
• decrypting the first encrypted vector to obtain an identifier associated with a second image used to generate the first encrypted vector.

A system comprising:

• one or more processors;
• and
• memory storing program instructions that, when executed by the one or more processors, cause the one or more processors to effectuate operations comprising:
• obtaining an encrypted search vector, wherein:
• the encrypted search vector is determined based on an image and a encryption key, and
• the encryption key is associated with an organization identifier based on a parameter associated with the organization identifier stored in a record;
• obtaining a first encrypted vector by searching a first encrypted vector set stored in a first database based on the encrypted search vector, wherein:
• for each respective encrypted vector of the first encrypted vector set, the respective encrypted vector is generated by encrypting a respective vector using the encryption key,
• a second encrypted vector set is stored in a second database,
• a second encrypted vector of the second encrypted vector set is encrypted without using the encryption key, and
• obtaining the first encrypted vector comprises selecting the first database for a search operation;
• and
• decrypting the first encrypted vector to obtain an identifier associated with data used to generate the first encrypted vector.
