Abstract
In embodiments of the present invention improved capabilities are described for providing data protection through the detection of tags associated with data or a file. In embodiments the present invention may provide for a step A, where data may be scanned that is intended to be communicated from the client computing facility. In response to step A, at step B, restricted data may be identified by identifying an absence of a tag associated with the data. And finally, in response to step B, at step C, an interruption to the intended communication may be caused.
Claims25
A computer program product embodied in a non-transitory computer readable medium that, when executing on one or more computing devices, performs the steps of:
- scanning a number of data items on a client computing facility for target content, wherein the target content includes restricted data;
- tagging one or more of the data items that do not contain the target content with a tag that is cryptographically signed;
- scanning data that is intended to be communicated from the client computing facility;
- identifying the restricted data by identifying an absence of the tag associated with the data, thereby providing an identification;
- and
- in response to the identification, causing an interruption in the intended communication of the data according to an enterprise policy including one or more control restrictions placed on communications of data from the client computing facility.
