Programmatically search and sensor sensitive information in a document for legal or security purposes to keep customer and employee information safe. Achieve full GDPR-compliance with Foxit’s powerful technology. Our redaction module applies annotations to block sensitive information in a document. Only a dark line will show in the place of the content in the front-end and no sensitive data is kept in the meta information. Our technology utilizes a process that ensures redacted material is deleted and the blacked out (redacted) areas become images, stopping someone being able to access the sensitive information underneath.
A digital signature is a digitally generated representation of a person’s identity through either an image of a persons signature or a computer generated typed signature which verifies a person’s identify and authenticates the contents of a document. In technical terms digital signatures are generated public key encryption that confirms a person’s identity in order to substantiate a document for legal or other purposes. Digital signatures can happen at page or document level depending on regulation and company standards.

PDF linearization is a quick web viewing format which displays pages instantly without having to wait for an entire file to be completely downloaded. To make use of this feature, PDF SDK for Web’s viewer checks at the initialization stage to programmatically detect if it is a linearization document. If it is, the Web viewer uses the fast web view mode (AsyncReaderCallback) to request the data. Otherwise, it follows the normal process mode.
If you experience slow page loading with PDF SDK for Web, use Chrome Dev Tools to inspect your Network activity to check if the slowness is related to repeat file loading. If so, you should consider using a cache policy on static assets to optimize repeat page load speed. PDF SDK for Web allows a temporary and permanent cache on files. The cache code sample is available at ..\examples\PDFViewCtrl\service-worker in the Web SDK package.
