Electronic document processing logic coupled to a computer and to a quarantine is operable to identify an encrypted electronic document received at the computer; determine whether the key server stores particular decryption data, or credentials to access decryption data, that can decrypt the encrypted electronic document; in response to determining that the key server does not store particular decryption data that can decrypt the encrypted electronic document: store the electronic document in the quarantine; notify one of the users; receive from the one of the users the particular decryption data; decrypt the electronic document; scan the electronic document to identify specified content in the electronic document; and perform one or more responsive actions based on the specified content. As a result, encrypted content in documents or e-mail can be decrypted, scanned for viruses, malware, or prohibited content, and re-encrypted or delivered.

Processing encrypted electronic documents

Mutual authentication systems and methods are described that comprise an authenticating server that is available across a network and capable of authenticating a user based on credentials provided by the user. An embeddable object provided by the authenticating server and containing a passphrase that identifies the server to the user. A credentials entry mechanism identifies the user to the authenticating server. A user device displays an Outer Page that can request authentication. The authenticating server verifies the source of the request and provides the passphrase to the user device. The display of the passphrase confirms the identity of the authenticating server to the user. The source of the request can be verified using a secure cookie. The embeddable object can be provided in a second page and can prevent display of the passphrase if user input is not directed to the second page.

Mutual authentication

Embodiments are described that leverage commonly used HTML tags to enable the transfer of large quantities of data in a network. Embodiments are described where large amounts of data can be sent to a server by fragmenting data into small portions and encoding each portion as part of a URL contained in, for example, the src attribute of an &#x3c;img&#x3e; tag. The path of this URL can refer to a predetermined resource contained on the server that is responsible for retrieving fragments of data from the requested URL. Each fragment of data can be sent together with whatever additional pieces of information are required by the server to correctly reassemble the portions to obtain the original, defragmented data. Methods are described that enable a client to communicate an arbitrarily large amount of data to a server using only the GET method.

Method and apparatus for transmitting arbitrarily large amounts of data over the internet

An apparatus, method, and computer-readable media capable of encrypting and unencrypting secure documents with multiple passwords and/or fallback keys. Embodiments allow documents to unencrypt themselves or be able to be unencrypted with multiple passwords. Methods embodiments include the creation of self-encrypted documents that provide for multiple password decryption, and may include the automatic generation of at least one fallback key to facilitate unencryption of documents.

Multiple password documents

An apparatus, method, and computer-readable media capable of encrypting and decrypting secure documents with multiple passwords and/or fallback keys. Embodiments allow documents to decrypt themselves or be able to be decrypted with multiple passwords. Methods embodiments include the creation of self-encrypted documents that provide for multiple password decryption, and may include the automatic generation of at least one fallback key to facilitate decryption of documents.

Fallback key retrieval

The invention involves a method for an Applet to be stored on a hard drive attached or available to a computer, such that the Applet is available to other programs running on the same computer wishing to make us of the Applet without transferring the Applet over the Internet.

System and method for applet caching

An apparatus, method, and computer-readable medium capable of extracting a payload file or files from a platform-independent, self-extracting, encrypted document. Embodiments include the creation of platform-independent, self-extracting archives that may be encrypted or unencrypted, execution of a platform-independent self-extracting archive.
