The present invention operates by inputting into the client computer a linkage code (a machine readable code such as a bar code symbol or a human-readable alphanumeric text string) that includes a server identification code and an item identification code. The client computer then extracts the server identification code, and obtains from local cache or from the routing server a URL template associated with the server identification code. The URL template includes the name of an information server and at least one parameter field to be completed by the client computer. The URL template is completed by the client computer by filling in at least the item identification code, and the completed URL template is then sent to the information server named therein as a primary content URL request.

System and method of using machine-readable or human-readable linkage codes for accessing networked data resources

A method of accessing electronic resources via machine readable data embedded on a document which comprises compressing input data with a transmitter adapted to save a first bandwidth using a compression method adapted to minimize utilization of bandwidth by the compressed input data while retaining substantially all information content of the input data and appending a compression flag to the compressed input data indicative of the compression method enabling a receiver to decompress the compressed input data. The compression step further comprises utilizing a compression dictionary adapted to map the elements and strings of the input data to minimized representations having redundancies deleted. The compression dictionary may be appended to the compressed input data (as cleartext or cyphertext) under circumstances where a bandwidth occupied by the appended compression dictionary is less than the bandwidth saved by the step of compressing the input data. The compression dictionary may also be selected by the receiver independently from the transmitter independently indexes, pointer registration, application restricted subsets or customized according to the input data content. Also the input data may be encrypted, and an encryption flag appended which is indicative of the encryption method enabling decryption via public or private key cryptosystems as well as utilizing various authentication techniques such as digital signatures to ensure that the document was created by a licensed user.

Method and system for accessing electronic resources via machine-readable data on intelligent documents

The present invention is a system and method for providing automated access to electronic information stored in a database in either a local or remote location. The system utilizes a machine-readable code printed on a document, referred to herein as an intelligent document since it stores information used to automatically access the information. The machine-readable symbol comprises encoded source data, wherein the source data comprises application launch information as well as file location information. The source data is encoded and printed, and then distributed by the vendor by any logical means to the end user. The end user then scans the code via appropriate code scanning (e.g. bar code scanning) equipment, decodes the raw decoded data, and the file location information is then used to access the appropriate file. In a preferred embodiment, a Web browser program is launched, and the URL of the vendor's Web site is accessed through the Internet. Local file retrieval may also be implemented on the client computer itself, as well as over an intranet or LAN environment. Additional user-specific demographic data such as the user's name and address may also be encoded in the machine-readable code when the document is specifically tailored for individual targeting, such as mailing labels. This demographic information is uploaded to the WWW site for use by the vendor. In addition, the present invention encodes security data, such as an encryption key, for use in secure data transmissions such as electronic commerce over the Internet.

Automatic access of electronic information through machine-readable

The present invention is a secure system and method for providing automated access to electronic information stored in a database in either a local or remote location. The system utilizes a machine-readable code printed on a document, referred to herein as an intelligent document since it stores information used to automatically access the information. The machine-readable symbol is encoded with source data (including a file location pointer) that is first obfuscated by generating a checksum of the source data, encrypting the source data by using the checksum as an encryption key, and assembling the checksum with the encrypted source data prior to encoding. The machine-readable symbol is then printed and distributed by the vendor by any logical means to the end user. The end user then scans the code via appropriate code scanning (e.g. bar code scanning) equipment, and de-obfuscates the scanned data by parsing the checksum, decrypting the remainder of the scanned data string (which includes the file location pointer) using the parsed checksum as a decryption key, computing a checksum of the decrypted data string, and comparing the computed checksum with the parsed checksum to determine the validity of the code. The file location pointer is then used to access the appropriate file. In a preferred embodiment, a Web browser program is launched, and the URL of the vendor's Web site is accessed through the Internet.
