Content Filtering. The content filtering ensures that only the previously filtered data with the information shared for the user reach their objectives and can be copied to or from removable media and PnP devices. In addition, the analysis and control of various file objects within the network/web communication (e-mails, instant messages, web forms, files, communication with social networks, telnet sessions) take place. ContentLock extracts from more than 120 file formats, the textual information and provides it for further classification. In addition to binary content analysis to determine the file type and the evaluation of document properties sensitive (text) content is recognized with the help of word matches, patterns of regular expressions (RegExp) and Boolean combinations (and/or/not conjunctions) of these criteria. Both an industry-specific keyword index, as well as RegExp templates (credit card numbers, banking/account information, etc.) are already included and can be extended.
In addition to the content detection in text-based data objects ContentLock can use an integrated optical character recognition (OCR) to examine text data in graphic files of more than 30 formats, as well as embedded images in documents other data objects, such as e-mails, instant messages, posts to social networks, etc..
With more than 30 recognized languages, using DeviceLock keyword dictionaries and regular expressions as well as dozens of other advanced features, this highly efficient OCR provides the ability to prevent data leakage of sensitive data.
