Abstract
Systems and methods in accordance with aspects of the present invention can be implemented to prevent automated, semi-automated, or manual searching, indexing, copying, and surveillance of electronic content, e.g., content in online documents or pages. Such systems and methods can also enable a human user to see the electronic content properly on a display, while the content remains unintelligible to computer programs. Thus, in accordance with the present invention, a computer application and a human user can interpret or “see” an electronic document differently.
Claims30
A method of encrypting text in electronic content carried out by a computer having one or more processors executing computer program code stored in at least one non-transitory storage device, the method comprising:
- accessing electronic text from the at least one storage device;
- generating a character encrypted electronic text using a non-standard text encoding scheme to electronically reassign character codes of the electronic text;
- and
- generating a matching character encrypted font configured to enable an output device to display the character encrypted electronic text in unencrypted form without decrypting the character encrypted text.
A computer program product stored in at least one storage device and executable by at least one processor to perform a method of encrypting text in electronic content, the method comprising:
- accessing electronic text from the at least one storage device;
- generating a character encrypted electronic text using a non-standard text encoding scheme to electronically reassign character codes of the electronic text;
- and
- generating a matching character encrypted font configured to enable an output device to display the character encrypted electronic text in unencrypted form without decrypting the character encrypted text.
A character encryption system comprising:
- at least one storage device including an electronic text;
- an encryption application executable by at least one processor to generate matching character encryption and decryption keys and a matching character encrypted font;
- and
- an encryption module executable by at least one processor to character encrypt the electronic text using the matching character encryption and decryption keys,
- wherein, using the matching character encrypted font, the character encrypted electronic text can be displayed at an output device in unencrypted form without decrypting the character encrypted text.
A character encrypting user input device, comprising:
- one or more processors configured to execute computer program code stored in at least one non-transitory storage device;
- at least one user input mechanism;
- and
- an encryption module executable by the one or more processors to character encrypt electronic textual inputs received via the at least one user input mechanism, using a non-standard text encoding scheme to electronically reassign character codes of the received electronic textual inputs.
