Application controlled encryption of web browser cached data

An apparatus for improving security of confidential data, comprising:

• a processor coupled to a memory, the processor executing,
• a first set of codes for causing a computer to receive a decryption component for secure communication of confidential data from a server;
• a second set of codes for causing the computer to receive a webpage containing encrypted content;
• a third set of codes for causing the computer to cache the webpage and the encrypted content;
• a fourth set of codes for causing the computer to present confidential data by decrypting the encrypted content with the decryption component;
• and
• a fifth set of codes for causing the computer to delete the decryption component upon a session terminating event, wherein the session terminating event comprises a time expiration condition.

An apparatus for improving security of confidential data, comprising:

• a networked computing platform;
• a browser component executed by the networked computing platform for rendering a webpage;
• a cache memory for caching a session key, a webpage containing encrypted content, and a decryption algorithm,
• wherein the browser utilizes the cache memory to present confidential data by decrypting the encrypted content with the decryption component in response to a user command to return to a previously rendered webpage, and to delete the session key to prevent subsequent decryption of the encrypted content in cache memory.
