  • Patent number: 10114851
    Abstract: Systems and methods for verifiable, private and secure omic analysis are provided. Secure multiparty computation techniques can be utilized to enable two parties to perform an omic transaction, such as determining genetic compatibility with one another, by jointly computing a result without either party disclosing their genetic information to the other. Privacy-preserving techniques to ensure authenticity of each party's omic data and metadata are also provided. Personalized matching scores can be computed, in which each party's score is weighted to reflect user preferences associated with the matching analysis.

  • Publication number: 20170242961
    Abstract: Systems and methods for conducting secure, privacy-preserving, verifiable omic transactions are provided. An omic service may authenticate one or more individual users and store each users omic information as encrypted data, without storing decryption keys, and also ensure fidelity and correct correspondence of each user's data with the user. A dedicated private virtual appliance can be instantiated to obtain encrypted omic data, query each user for decryption keys, decrypt the user omic data, perform an omic calculation, report results and terminate itself, thereby erasing all copies of decrypted user omic data. Alternatively, the appliance can operate with user-managed genome storage. A genome-on-a-stick construct facilitates end user interaction with such omic service providers.
