25 Mar 2002-
TL;DR: In this paper, the authors propose a system and method for communicating information between a first party and a second party, comprising the steps of receiving, by an intermediary, an identifier of desired information and accounting information for a transaction involving the information from the first party, and negotiating, by the intermediary, a comprehension function for obscuring at least a portion of the information communicated between the first parties and the second parties.
Abstract: A system and method for communicating information between a first party and a second party, comprising the steps of receiving, by an intermediary, an identifier of desired information and accounting information for a transaction involving the information from the first party, transmitting an identifier of the first party to the second party, and negotiating, by the intermediary, a comprehension function for obscuring at least a portion of the information communicated between the first party and the second party. The data transmission may be made secure with respect to the intermediary by providing an asymmetric key or direct key exchange for encryption of the communication between the first and second party. The data transmission may be made secure with respect to the second party by maintaining the information in encrypted format at the second party, with the decryption key held only by the intermediary, and transmitting a secure composite of the decryption key and a new encryption key to the second party for transcoding of the data record, and providing the new decryption key to the first party, so that the information transmitted to the first party can be comprehended by it.

Abstract: A method for providing unequal allocation of rights among agents while operating according to fair principles, comprising assigning a hierarchal rank to each agent; providing a synthetic economic value to a first set of agents at the a high level of the hierarchy; allocating portions of the synthetic economic value by the first set of agents to a second set of agents at respectively different hierarchal rank than the first set of agents; and conducting an auction amongst agents using the synthetic economic value as the currency. A method for allocation among agents, comprising assigning a wealth generation function for generating future wealth to each of a plurality of agents, communicating subjective market information between agents, and transferring wealth generated by the secure wealth generation function between agents in consideration of a market transaction. The method may further comprise the step of transferring at least a portion of the wealth generation function between agents.

TL;DR: A mobile payment platform and service as mentioned in this paper provides a fast, easy way to make payments by users of mobile devices and interfaces with non-mobile channels and devices such as e-mail, instant messenger, and Web.
Abstract: A mobile payment platform and service provides a fast, easy way to make payments by users of mobile devices. The platform also interfaces with nonmobile channels and devices such as e-mail, instant messenger, and Web. In an implementation, funds are accessed from an account holder s mobile device such as a mobile phone or a personal digital assistant to make or receive payments. Financial transactions may be conducted on a person-to-person (P2P) or person-to-merchant (P2M) basis where each party is identified by a unique indicator such as a telephone number or bar code. Transactions may be requested through any number of means including SMS messaging, Web, e-mail, instant messenger, a mobile client application, an instant messaging plug-in application or widget. The mobile client application, resident on the mobile device, simplifies access and performing financial transactions in a fast, secure manner.

16 Apr 2003TL;DR: In this paper, the authentication service allows a card issuer to verify a card's identity using a variety of authentication methods, such as with the use of tokens, and notifying a merchant whether the cardholder's authenticity has been verified.
Abstract: A payment authentication service authenticates the identity of a payer during online transactions. The authentication service allows a card issuer to verify a cardholder's (110) identity using a variety of authentication methods, such as with the use of tokens. Authenticating the identity of a cardholder (110) during an online transaction involves querying an access control server to determine if a cardholder (110) is enrolled in the payment authentication service, requesting a password from the cardholder, verifying the password, and notifying a merchant whether the cardholder's (110) authenticity has been verified. Systems for imp lementing the authentication service in which a cardholder (110) uses a mobile device capable of transmitting messages via the Internet are described. Systems for implementing the authentication service in which a cardholder (110) uses a mobile device capable of transmitting messages through voice and messaging channels is also described.

TL;DR: This paper suggests ways to solve currently open problems in cryptography, and discusses how the theories of communication and computation are beginning to provide the tools to solve cryptographic problems of long standing.
Abstract: Two kinds of contemporary developments in cryptography are examined. Widening applications of teleprocessing have given rise to a need for new types of cryptographic systems, which minimize the need for secure key distribution channels and supply the equivalent of a written signature. This paper suggests ways to solve these currently open problems. It also discusses how the theories of communication and computation are beginning to provide the tools to solve cryptographic problems of long standing.

TL;DR: It is argued that insertion of a watermark under this regime makes the watermark robust to signal processing operations and common geometric transformations provided that the original image is available and that it can be successfully registered against the transformed watermarked image.
Abstract: This paper presents a secure (tamper-resistant) algorithm for watermarking images, and a methodology for digital watermarking that may be generalized to audio, video, and multimedia data. We advocate that a watermark should be constructed as an independent and identically distributed (i.i.d.) Gaussian random vector that is imperceptibly inserted in a spread-spectrum-like fashion into the perceptually most significant spectral components of the data. We argue that insertion of a watermark under this regime makes the watermark robust to signal processing operations (such as lossy compression, filtering, digital-analog and analog-digital conversion, requantization, etc.), and common geometric transformations (such as cropping, scaling, translation, and rotation) provided that the original image is available and that it can be successfully registered against the transformed watermarked image. In these cases, the watermark detector unambiguously identifies the owner. Further, the use of Gaussian noise, ensures strong resilience to multiple-document, or collusional, attacks. Experimental results are provided to support these claims, along with an exposition of pending open problems.

TL;DR: Automation of the way the authors pay for goods and services is already underway, as can be seen by the variety and growth of electronic banking services available to consumers.
Abstract: Automation of the way we pay for goods and services is already underway, as can be seen by the variety and growth of electronic banking services available to consumers. The ultimate structure of the new electronic payments system may have a substantial impact on personal privacy as well as on the nature and extent of criminal use of payments. Ideally a new payments system should address both of these seemingly conflicting sets of concerns.
