Methods and systems for cryptographically secured decentralized testing
A method of cryptographically secured decentralized testing includes receiving, by a computing device and from a secure test apparatus, an output of a cryptographic function of a secret test result identifier, authenticating the output, and recording, in a data repository, an indication of a test result as a function of the output.
1. A method of cryptographically secured medical testing, the method comprising:
receiving, by a computing device and from a secure test apparatus, an output, wherein:
the secret test result identifier is encoded with an error correction code;

the output is generated as a function of a cryptographic function of the secret test result identifier, wherein:
the cryptographic function further comprises a privacy-preserving protocol; and
the privacy-preserving protocol further includes:
publishing, by the computing device, a commitment to a plurality of secret test result identifiers; and
receiving, by the computing device, a one-out-of-many cryptographic proof of knowledge of an included secret test identifier of the plurality of secret test identifiers;
authenticating the output as a function of the cryptographic function; and
recording, in a data repository, a test result as a function of the authenticating.
2. The method of claim 1 , wherein the output includes a cryptographic hash of the secret test result identifier.
3. The method of claim 1 , wherein the output includes a secure proof of the secret test result identifier.
4. The method of claim 1 further comprising generating a commitment to the secret test result, and wherein the secure proof is a proof of the commitment.

6. The method of claim 1 , wherein the privacy-preserving protocol further includes:
storing, by the computing device, a plurality of secret test results;
receiving, by the computing device, an oblivious transfer request; and
transmitting, by the computing device an included secret test result of the plurality of secret test results using an oblivious transfer protocol.
7. The method of claim 1 , wherein the secure test apparatus further comprises a test identifier that is visible prior to testing, and wherein receiving the oblivious transfer request further comprises receiving the test identifier.
