Abstract: Embodiments described herein provide cryptographic techniques to enable a recipient of a signed message containing encrypted data to verify that the signer of the message and the encryptor of the encrypted data are the same party, or at the least, have joint possession of a common set of secret cryptographic material. These techniques can be used to harden an online payment system against interception and resigning of encrypted payment information.

Abstract: Techniques are described for generating a verified data package. An example method includes receiving data including biographical information and an associated portrait. The method further includes causing a prompt for a user to capture a self-portrait photograph to be displayed based at least in part on receiving the data. The method further includes receiving the self-portrait photograph based at least in part on the displayed prompt. The method further includes causing data and the self-portrait photograph to be transmitted to a server. The method further includes receiving, from the server, a verified data package comprising the biographical information, the portrait, and an attestation that the self-portrait photograph and the portrait are the user.
