ABSTRACT:
BACKGROUND OF INVENTION
1. Field of Invention
The present invention relates generally to improvements in the operation and performance of client-server type internetworked computer systems of global extent, such as the Internet, and more particularly to a novel Internet-based information system and method which enables millions of time-constrained competitions, contests or transactions, among the mass population, in a fundamentally fair and secure manner, using globally time-synchronized client subsystems and information servers having extreme accurate client-event resolution independent of variable network latency.
2. Brief Description of the State of the Art
While the role of cooperation has a secure place in the history of mankind, so too does the role of competition. Few will disagree that, over the course of time, human beings have competed in widely diverse ways for both tangible and intangible objects of need and desire. Such objects of need or desire have included: food; shelter; land; rewards; prizes; natural resources; sexual partners; fame; fortune; diversion or recreation, such as sport; and ultimately, survival.
While the nature of man does not appear to have changed fundamentally over the course of time, it is clear that his choice of tools and weapons have changed in step with his increase in technological skill and knowledge.
For example, in the late 1960's, the globally-extensive information infrastructure, now referred to as the Internet, was developed by the United States Government as a tool for national defense and survival in world of intense global competition and military struggle. Ironically, some thirty years later, with the technological development of the HyperText Transport Protocol (HTTP), the HyperText Markup Language (HTML), and the Domain Name System (DNS), a globally-extensive hyper-linked database referred to as the World Wide Web (WWW) has quickly evolved upon the infrastructure of the Internet. By virtue of the WWW, billions and even trillions of information resources, located on millions of computing systems at different locations on Earth, have been linked in complex ways serving the needs and desires of millions of information resource users under the domains .net, .edu, .gov, .org, .com, .mil, etc. of the DNS.
The overnight popularity and success of the WWW can be attributed to the development of GUI-based WWW browser programs which enable virtually any human being to access a particular information resource (e.g. HTML-encoded document) on the WWW by simply entering its Uniform Resource Locator (URL) into the WWW browser and allowing the HTTP to access the document from its hosting WWW information server and transport the document to the WWW browser for display and interaction. The development of massive WWW search engines and directory services has simplified finding needed or desired information resources using GUI-enabled WWW browsers.
Without question, a direct consequence of the WWW, the GUI-based WWW browser, and underlying infrastructure of the Internet (e.g. high-speed IP hubs, routers, and switches) has been to provide human beings with a new set of information-related tools that can be used in ever expanding forms of human collaboration, cooperation, and competition alike.
Over the past several years, a number of WWW-enabled applications have been developed, wherein human beings engage in either a cooperative or competitive activity that is constrained or otherwise conditioned on the variable time. Recent examples of on-line or Web-enabled forms of time-constrained competition include: on-line or Internet-enabled purchase or sale of stock, commodities or currency by customers located at geographically different locations, under time-varying market conditions; on-line or Internet-enabled auctioning of property involving competitive price bidding among numerous bidders located at geographically different locations; and on-line or Internet-enabled competitions among multiple competitors who are required to answer a question or solve a puzzle or problem under the time constraints of a clock, for a prize and/or an award.
In each of the above Internet-supported applications or processes, there currently exists an inherent unfairness among the competitors due to at least six important factors, namely: (1) the variable latency of (or delay in) data packet transmission over the Internet, dependent on the type of connection each client subsystem has to the Internet infrastructure; (2) the variable latency of data packet transmission over the Internet, dependent on the volume of congestion encountered by the data packets transmitted from a particular client machine; (3) the vulnerability of these applications to security breaches, tampering, and other forms of manipulation by computer and network hackers; (4) the latency of information display device used in client subsystems connected to the Internet; (5) the latency of information input device used in client subsystems connected to the Internet; and (6) the latency of the central processing unit (CPU) used in the client machine.
Regarding the first unfairness factor, it is important to point out that the network latency over the Internet varies over the course of the day and in response to network usage. Expressed differently, the time for a transmitted data packet to travel between a first client computer to a particular information server on the Internet will be different from the time for a transmitted data packet to travel between a second client computer to the same information server on the Internet. This time variance in the network latency on the Internet, referred to as the “variable network latency”, must necessarily be modeled a non-deterministic process subject to the laws and principles of random (e.g. stochastic) processes. This has a number of important consequences for Internet-supported forms of time-constrained competition.
For example, in connection with Internet-supported competitions (e.g. games) involving a plurality of competitors or competitors, U.S. Pat. No. 5,820,463 attempts to compensate for network latency by measuring the average latency between all the client machines and then inserting intentional communication delays to make the average overall latency the same for all communications links. However, while this system equalizes the communication latency on average, it is wholly incapable of compensating for the random components of network latency (i.e. variable network latency) of the Internet. Consequently, even when practicing the methods disclosed in U.S. Pat. No. 5,820,463, the variable network latency of the Internet nevertheless introduces inherent sources of error into time-constrained competitions, thereby putting certain competitors at an unfair disadvantage, i.e. by virtue of their client computer connection to the Internet in relation to the information server supporting the time-constrained competition.
Regarding the second unfairness factor, it is important to point out that when Internet-supported competition involves a small number of competitors (e.g. 100 or less), the network latency should not be greatly affected by the competitors themselves, but rather will be more dependent on the types of connections the competitor's client machines have with the Internet and on network traffic and congestion as a whole. However, during Internet-supported competition involving massive numbers of competitors, as would exist during Web-based securities and commodities trading, and Web-based auctions, involving thousands or even millions of human beings are all competing simultaneously. Because of the simultaneous start time and the expected distribution of responses, the system will be subject to two intense impulses of traffic, one slightly before the competition start, and the other at the mean response time. It is necessary for the time-constrained competition system to be able to adequately handle this intense bandwidth.
As larger numbers of competitors are becoming involved in a time-constrained competition, it becomes more likely tha
