A server computer receives from a resource provider device transaction data, a first set of wireless communication signals available to the resource provider device, a second set of wireless communication signals available to the resource provider device, and a sound level detected by the resource provider device. The server computer retrieves from a user device a first set of wireless communication signals available to the user device, a second set of wireless communication signals available to the user device, and a sound level detected by the user device. The server computer computes a score based on the first sets of wireless communication signals, the second sets of wireless communication signals, and the detected sound levels. The server computer transmits to an authorization computer the transaction data and the score, thereby causing the transaction to be processed or terminated based on the transaction data and the score.

An insensitive summary of an encrypted electronic document, such as email, is provided. The insensitive summary provides a summary of the encrypted electronic document without providing sensitive information, such as passwords. The electronic document may be an email, text (such as in a word processing file), spreadsheet and/or presentation. Natural language processing methods, such as parts of speech (POS) tagging, word clustering, regular expression evaluating, sensitive key word searching and/or other methods, may be used to identify and mask sensitive words before summarization and encryption of the electronic document. A user's efficiency in operating a computing device may be increased having an associated insensitive summary without compromising security of the encrypted electronic document. A user may direct a computing device to perform a search (or similarly categorize or use rules) to identify the encrypted electronic document by searching for contents of the associated insensitive summary.

The system and method of the present disclosure relates to data stored in a common database of a network for parallel processing by multiple processors or processing centers. As consumers and business continue to generate more and more data, the amount of data being stored across networks and computing environments increases. To monitor and process increasingly large amounts of data, the system and method of the present disclosure utilizes the atomicity of certain databases and storage devices to efficiently identify and mark data for processing by a designated processor or processing center, such that the designated processor or processing center is responsible for processing the identified and marked data. Consequently, the system ensures that no two processors or processing centers are processing the same data at the same time without the use of schedulers, queues or other conventional techniques.
