    Abstract: A method, mobile device, and PKI are provided for enrolling a mobile device into a PKI domain for certificate management is provided. A first asymmetric key pair and a unique identifier is established in a device. The first asymmetric key pair includes a public key and a private key. The public key and the unique identifier are transferred to the PKI domain. The public key and the unique identifier are imported into the PKI domain. The device generates a second asymmetric kay pair and sends a certificate signing request (CSR) that is protected with the digital signature of the first asymmetric key pair. The CSR is transferred to the PKI domain. The PKI domain authenticates the CSR using the first public key and the unique identifier. Upon validation, the PKI domain issues a certificate to the device.

    Abstract: Disclosed is a radio system, method, and device for a mobile station to indicate to an authentication controller, in an authentication response message, which of a plurality of group key link layer encryption keys (GKEK)s it currently has in its possession, and to work with the authentication controller to more intelligently manage multiple GKEKs. The authentication controller can use the information obtained from the authentication response message to determine which of a plurality of GKEKs to advertise in a key announcement broadcast. Furthermore, individual requests for a future LLE key (LEK) to be used for link layer encryption (LLE) encrypting and decrypting inbound and outbound group communications between base station(s) and mobile station(s) are responded to with a broadcast GKEK-encrypted transmission including the future LEK. Only the requesting mobile station transmits an acknowledgment packet in response to the broadcast.

    Abstract: A process of redacting records based on a contextual correlation with a previously redacted record. In operation, an electronic computing device obtains redaction metadata associated with a previously redacted record and uses the redaction metadata to identify a segment within an unredacted record that was redacted to generate the previously redacted record. The device then processes the segment to detect characteristics of a person or the object captured in the unredacted record and further redacted in the redacted record. The device also determines a context in which the redacted person or object was captured within the segment of the unredacted record. The device then redacts a person or object captured in other unredacted records when such person or object is contextually related to the redacted person or object captured in the unredacted record corresponding to the previously redacted record.

    Abstract: A process of extending retention periods of records. In operation, an electronic computing device identifies a retention period associated with the record. The device obtains information related to a future event. The information includes a time period during which the future event is predicted or scheduled to occur and a location at which the future event is predicted or scheduled to occur. When the device determines that the record is contextually related to the future event based at least in part on the time period or the location of the future event, the retention period associated with the record is extended. The device may also automatically extend retention periods of records based on a number of other retention-related factors associated with the record including recording content, record trustworthiness, recording time, recording location, recording data type, recording source, recording officers' profile and their association, crime statistics, incident severity, and the like.
