Problems solved by technology

First, any wireless communication is much easier to intercept than a wired transmission
Second, and perhaps more importantly, most palmtop computers have far less processing power than even general-purpose desktop computers
As such, they do not have the speed or capacity required to handle high-strength SSL encryption, which involves encryption of entire documents

Embodiment Construction

[0018] refer to figure 1 , providing a generalized system by which individual wireless palm-type terminals 10 can connect to their respective Web servers 56 . The mobile terminal 10 transmits / receives 12 to and from the satellite 13 through the antenna 11 , and connects to the satellite antenna 33 through the path 43 , and then connects to the Web server 56 through the wireless terminal receiver 45 . It should be noted that the term "personal hand-held device" is used to generally cover a variety of hand-held devices. This includes cellular phones and related wireless devices, smartphones and Internet screen phones. The encryption and decryption functions performed in the palm computer device 10 and server 56 have been discussed generally above and will be discussed in detail below. Server 56 may have an associated I / O display or display computer 57 through which a user can interface with server 56 for maintenance, updates, error correction, and the like.

Abstract

Encryption is provided in wireless personal palm type computer devices for Internet transmitted documents despite the limited data processing and memory functions in such devices. The palm type device initially encrypts only a portion of a text document which is then wirelessly transmitted to the server computer which normally functions as the Web server, i.e. the server through which Web computer terminals are wired or connected into the Web. This Web server then further encrypts the received text document and then further transmits this further encrypted document to a terminal in said network. Preferably, the further encryption in the server involves two steps: decrypting the lower level encryption (necessitated by the limited CPU and memory resources in the palm device) to restore the text document at the server before the server may then re-encrypt the whole document using a higher level conventional 128 bit Web encryption protocols such as SSL.

Description

technical field [0001] The present invention relates to the protection of data transmitted from a wireless terminal, especially a palmtop computer device, to a network computer terminal, such as a Web or Internet (used alternatively) terminal. Background technique [0002] The past decade has been marked by a technological revolution driven by the combination of the data processing industry and the consumer electronics industry. Again, this influence has contributed to the advancement of technologies that were already known and applicable but relatively static during these years. A major one of these technologies is the distribution of documents, media and programs related to the Internet or the Web. The combination of electronic entertainment and consumer industries with data processing has exponentially increased the demand for a wide range of communication distribution channels, and the Web or Internet has begun a significant period of expansion. With this expansion, bu...
