Abstract

Data security for processing data or securing browser-input data operates on security sensitive content which is extracted, then either encrypted or stored in remote extract stores, and processed separate from remainder data. Extracted data, in one system, is remotely stored. Other methods attach, append, add or insert an encrypted version of the extract content to the document. The browser system operates with an extract store. Remainder data is sent to the addressee or designated client by the web server. The addressee is permitted to retrieve the extracted data from said extract store only with a security clearance and hence, reconstruct the source input data with the extract data. In other systems, the addressee reconstructs the input by decryption and integration. The browser method extracts data, facilitates the storage, forwards the remainder data to a target. Financial data or credit card scrubber may use pop-up windows for enablement.
