Abstract

A method may include, receiving, at a server device and from a requesting computing device associated with a requesting user, a request for a data item. The data item configured may be configured as a data structure and include an encrypted data payload; metadata identifying a source of the payload and when the data payload was captured; and a token identifying an owner of the data item and access rights to the data item. The method may include parsing he token to identify the owner of the data item; transmitting the request for the data item to a computing device associated with the owner; receiving a response from the computing device. The response may indicate the requesting user may access the data item, and in response, transmit a decryption key to the requesting computing device for the encrypted data payload. The method may include updating the token.
