Abstract: Advertising with machine-readable (mobile) codes by printing a machine-readable code on a print publication, which is then scanned with a device, and the URL of an ad management computer and an ad identification number are decoded from the mobile code. This URL is used to send the ad identification number to the ad management computer, which accesses a database to determine if a link limit for that ad identification number has been exceeded. If not exceeded, then a destination URL of an advertisement web page associated with the ad identification number in the database is sent to the device so it can connect to that URL. If the link limit has been exceeded, then the destination URL from the database is not sent, but is used as an argument to generate search web page, and the ad content management computer transmits the generated search web page to the device.

Abstract: The present invention provides methods and systems for authenticating identification documents. We also teach an identification document including two or more digital watermarks. The watermarks correspond with each other or with indicia carried by the identification document. The correspondence can be verified to determine authenticity. We also provide digital watermark detection methods and systems to identify the different watermarks through embedded orientation components. We then focus watermark message-decoding efforts on areas identified as likely including watermark orientation components. In one implementation we provide a watermark detection trigger to identify so-called legacy documents. The trigger may indicate the presence or expected absence of a digital watermark. In other implementations we provide a versatile document authenticator to toggle between watermarking and non-watermarking authentication processes depending on a detection trigger.

Abstract: A method for providing remote access to on-line resources comprising the steps of encoding address and access information and optional source identification information into a format suitable for embedding onto a document, the format comprising one or two-dimensional bar codes or printed matter, embedding the encoded information onto a document, scanning the document with a scanner enhanced remote control unit comprising a scanning system adapted to obtain an image of the embedded information and a transmission system adapted to transmit the scanned information, transmitting the scanned information, receiving the transmitted information, optionally processing the received information, optionally collecting the user demographic and source identification information, retrieving the on-line resource, and displaying the on-line resource to a user.

Abstract: A method of and system for providing a primary content file to a client device from a wireless device by using a stored code list service. In this case, the wireless device is used only to collect and transmit linkage codes to a list server (the linkage codes can be later accessed by any client device on the internet), and not to actually retrieve and display content associated with the linkage code.

Abstract: A network-based system and method permit a publisher to generate and encode content to be readily accessed by codes or indicia, such as bar codes, and which may be associated with advertising related to the content via the codes. The system supports composer, reader, discovery, and static web page interfaces for permitting users to act as publishers, readers, or browsers, using the codes for efficient and rapid access of content.

Abstract: 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.

Abstract: 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.

Abstract: Method and apparatus for determining that a first unit of data associated with a first party has not been modified since a specified point in time. A method includes the steps of (a) providing the first unit of data and (b) generating a second unit of data from the first unit of data, the second unit of data being expressive of an information content of the first unit of data. The method further includes a step of (c) generating a time indication for specifying a point in time, the time indication being generated with time generation means having a time is settable by a second party other than the first party. That is, the time generation means is secured and cannot be altered or changed by the first party. The method further includes a step of (d) encrypting the second unit of data and the generated time indication to generate a third unit of data.
