Abstract
Example embodiments of the present invention relate to a method, an apparatus and a computer-program product for implementing digital disappearing ink. An example method includes receiving portions of a data stream transmitted from a source and analyzing the portions of the data stream. Based on the analysis, the method includes performing an action with respect to an object tag according to the analysis.
Claims20
A computer-implemented method for transforming a cookie from a user data stream, the method comprising:
- intercepting a cookie from a user data stream before the cookie escapes a private network, wherein the cookie includes content;
- determining whether the content within the cookie includes private information, sensitive information, and an object tag defining an action with respect to the cookie according to a policy associated with the object tag, wherein the determining includes performing a lexical analysis of the content of the cookie;
- performing a transformation of the cookie according to the lexical analysis, wherein the transformation includes masking the private information and the sensitive information within the cookie;
- and
- sending the transformed cookie from the private network to a destination device.
An apparatus for transforming a cookie from a user data stream, the apparatus comprising:
- a receiver module configured to intercept a cookie from a user data stream before the cookie escapes a private network, the cookie includes content;
- an analysis engine configured to perform a lexical analysis of the content of the cookie to determine whether the content within the cookie includes private information and sensitive information;
- and
- a transformation module configured to perform a transformation of the cookie according to the lexical analysis and a sending of the transformed cookie from the private network to a destination device, wherein the transformation includes masking the private information and the sensitive information within the cookie.
A computer program product including a non-transitory computer-readable storage medium encoded with computer-program code that, when executed on a processor of a computer, cause the computer to transform a cookie from a user data stream, the computer-program product comprising:
- computer program code for intercepting a cookie from a user data stream before the cookie escapes a private network, wherein the cookie includes content;
- computer program code for determining the content within the cookie includes private information, sensitive information, and an object tag defining an action with respect to the cookie according to a policy associated with the object tag, wherein the determining includes performing a lexical analysis of the content of the cookie;
- computer program code for performing a transformation of the cookie according to the lexical analysis, wherein the transformation includes masking the private information and the sensitive information within the cookie;
- and
- computer program code for sending the transformed cookie from the private network to a destination device.
