Abstract
Techniques utilizing common encryption approaches for data from multiple parties enable those parties to discover information that is held in common by the parties without disclosing to any party information that is not held in common by the parties. Encrypted information for each party can be compared to determine which encrypted values match, and those encrypted values can be returned to any of the parties such that a party can determine which corresponding data the parties have in common without having access to any other data of any other parties.
Claims20
A method comprising:
- encrypting, using at least one processor operatively coupled with a memory, each email address of a first set of email addresses using an encryption scheme to create a first set of encrypted strings;
- sending the first set of encrypted strings to a remote computer;
- receiving a second set of encrypted strings from the remote computer, the second set of encrypted strings created using the first set of encrypted strings;
- determining from an encrypted string of the second set a corresponding unencrypted email address;
- and
- sending an email to the unencrypted email address.
A computer program product stored on a non-transitory computer-readable medium for processing information, the computer program product comprising:
- program code for encrypting, using at least one processor operatively coupled with a memory, each email address of a first set of email addresses using an encryption scheme to create a first set of encrypted strings;
- program code for sending the first set of encrypted strings to a remote computer;
- program code for receiving a second set of encrypted strings from the remote computer, the second set of encrypted strings created using the first set of encrypted strings;
- program code for determining from an encrypted string of the second set a corresponding unencrypted email address;
- and
- program code for sending an email to the unencrypted email address.
