Abstract: Digital Cameras configured to verify authenticity of digital photos taken with the digital camera and related methods and computer program products are provided. GPS information associated with a photograph taken with the digital camera is obtained. A checksum of pixels that make up the photograph and the obtained GPS information is generated. The generated checksum is encrypted using a private key associated with the digital camera so as to allow verification that the photograph has not been modified.

Abstract: Information related to telephone numbers is efficiently stored and retrieved by generating an index based on a portion of a telephone number for which information is to be stored or retrieved. For example, the portion of the telephone number can be a prefix of the telephone number. Information related to the telephone number is stored and retrieved in accordance with the generated index.

Abstract: Methods, systems, and computer program products collect and deliver call data associated with court ordered trap and/or traces. A method involves receiving a request to monitor calls to and/or from a target telephone number where the request includes request parameters such as the target telephone number. The method further involves storing the request where the target telephone number is stored in association with a court order and utilizing the request to identify and retrieve call records matching the request parameters. Utilizing the request to identify and retrieve call records matching the request parameters may involve creating a text file including the request parameters, reading the request parameters from the text file, monitoring call records for call records matching the request parameters, and storing call records that match the request parameters. The call records that match are stored in association with the court order and the target telephone number.

Abstract: Methods, systems, and computer programs for constructing a billing statement from detailed usage file (DUF) records received from an Incumbent Local Exchange Carrier (ILEC). A master file contains routing information associating each of a plurality of telephone numbering plan addresses plus additional telephone number digits (NPA-NXX) with a corresponding local access transport area (LATA). Telephone operator services (TOPS) assignment files are downloaded and used to edit the master file, thereby generating an enhanced master file. DUF records are downloaded. A set of enhanced DUF records is generated by filtering the downloaded DUF records. A rate table of customer price plans is applied to the set of enhanced DUF records and the enhanced master file to construct a billing statement.

Abstract: A consistency verification tool performs a consistency check on subscriber data records stored in the cellular telephone system. One such consistency check analyzes subscriber data records in a home location register (HLR) and a billing system to determine the presence of duplicate records. Duplicate records can be stored in a duplicate record file for later analysis. During the duplicate record consistency analysis, the consistency verification tool creates a record list. The record list can be a linked list structure for storing main records and duplicate records in a manner that facilitates identifying families of duplicate records. The consistency verification tool can also perform inter-device consistency checks. For example, the subscriber data stored on the HLR can be compared to the subscriber data stored in the billing system to ensure that the two systems have consistent subscriber data.

Abstract: One method involves receiving a search request that includes a date and phone number. A master index file is searched for the phone number. The master index file includes phone numbers associated with calls that occurred on the date in the search request. The master index file also includes the location of the first index record for the phone number in an index file. The index file includes an index record for each call record. Each index record includes a phone number from a call record and the location of the call record. In response to locating the phone number in the master index file, the index file is searched for each index record with the phone number. In response to locating an index record with the phone number, the call record associated with that index record is retrieved. A search result including each call record retrieved is returned.
