Techniques for managing activity logs in a manner that promotes user privacy

A non-transitory computer readable storage medium configured to store instructions that, when executed by a processor included in a centralized management hub, cause the centralized management hub to manage activity logs in a manner that promotes user privacy, by carrying out steps that include:

• receiving, from a peripheral device, information about activity detected by the peripheral device, wherein the information includes at least one activity tag;
• identifying a hash function;
• providing the at least one activity tag to the hash function to generate at least one hash value;
• encrypting, using an encryption key that is accessible to the centralized management hub, at least a subset of the information to produce encrypted information;
• and
• causing a server device to store, in an activity log associated with the centralized management hub, an activity log entry that includes:
• a timestamp corresponding to a time at which the activity log entry is stored,
• the at least one hash value, and
• the encrypted information.

A method for accessing activity logs, the method comprising, at a centralized management hub:

• receiving, from a peripheral device, a first request to obtain at least one activity log entry from an activity log, wherein the first request includes a timespan and at least one activity tag;
• identifying a hash function that was used to generate at least one hash value based on the at least one activity tag;
• providing the at least one activity tag to the hash function to generate at least one hash value;
• issuing, to a server device, a second request to obtain at least one encrypted activity log entry based on the timespan and the at least one hash value;
• receiving the at least one encrypted log entry from the server device;
• decrypting the at least one encrypted log entry using an encryption key to produce at least one decrypted log entry;
• and
• causing the peripheral device to display content derived from the at least one decrypted log entry.
