Systems and methods for use in appending log entries to data structures

A computer-implemented method for use in appending one or more log entries to a data structure, the method comprising:

• receiving, at a communication device, a log entry from a terminal, the log entry including a location of the terminal and a timestamp, the location and the timestamp specific to an interaction with a user associated with the communication device;
• signing, by the communication device, the log entry with a private key specific to the communication device;
• associating, by the communication device, the signed log entry with a unique identifier of the communication device;
• transmitting the signed log entry and the unique identifier to an identity provider (IDP);
• receiving, by the communication device, from the IDP, a signed, encrypted log entry;
• verifying, by the communication device, a signature of the signed, encrypted log entry based on a public key specific to the IDP from a secure element of the communication device;
• and
• appending the encrypted log entry to a digital identity included in the communication device.

A non-transitory computer-readable storage medium comprising executable instructions for use in appending one or more log entries to a data structure associated with a digital identity of a user, which when executed by at least one processor of a communication device, cause the at least one processor to:

• receive a log entry from a terminal, the log entry including a location of the terminal and a timestamp, the location and the timestamp specific to an interaction between the terminal and a user associated with the communication device;
• sign the log entry with a private key of a key pair specific to the communication device;
• transmit the signed log entry to an identity provider (IDP);
• receive, from the IDP, a signed, encrypted log entry;
• verify a signature of the signed, encrypted log entry based on a public key associated with a key pair specific to the IDP;
• and
• append the encrypted log entry to a digital identity included in the communication device.
