Secure teleprocessing bidding system5243515Abstract An improved system and apparatus for conducting secret bidding procedures. The apparatus provides for the reception of bidding data for a particular bid recipient in a particular division of a particular job. Once received, this information is stored and processed electronically. The bid information is collected until a preset date when the system automatically transmits a bid report detailing the bidders and their associated bids to each bid recipient. At a second preset date the system transmits a bid comparison report revealing only the amount of each bid to each of the bidders who submitted a bid for the particular division.

DeFrancesco '367 pertains to an automated financial data disclosure system, more specifically to a method and apparatus for audibly eliciting input information and for audibly announcing financial disclosure information computed on the basis of the input information. Sibley '552 relates to a trade exchange system and in particular to a world trade exchange having a central exchange host for providing international commodity information and a plurality of local exchanges in various sites around the world wherein a plurality of user computer terminals coupled to each of the local exchanges can request and receive data representing marketing information directly from the central exchange host and transmit data representing bids and offers to its local exchange. SUMMARY OF THE INVENTION The invention provides apparatus for the reception, storing and processing, via currently available electronic communication means including telephone, modem or fax, of bidding data. Once received, the bid is stored electronically, either through the use of analog to digital translators, or the intervention of a human operator. The bid information is collected and stored until a preset date and/or time when the system automatically and simultaneously transmits bid documents containing all pertinent bid information to each of the bid recipients subscribing to the system. At a second preset date the system simultaneously transmits a bid comparison report to each of the bidders. This comparison report reveals the amount of each bid without revealing the identity of any particular competitor. The apparatus consists of a central processing unit with sufficient power to handle the volume of transactions for any given specific situation, a keyboard input unit, video display unit, and modem/fax board connected to the central processing unit, and an associated printer capable of printing at a sufficient speed for the quantity of transactions involved. OBJECTS OF THE INVENTION The principal object of the present invention is to provide a secure teleprocessing bidding system in which bid procedure violations are eliminated by ensuring the secrecy and confidentiality of bids until an appropriate predetermined time. A further object of this invention is to provide a method of educating subcontractors about their competitor's bids without destroying the bidding process. Another object of the invention is to provide a secure bidding system that is adaptable and conformable to the basic mechanics of the bidding process as it currently exists. A further object of the invention is to provide a user friendly secure bidding system. A further object of this invention is to provide a bidding system that promotes fairness in bidding on publicly financed jobs. BRIEF DESCRIPTION OF THE DRAWINGS The foregoing and other objects will become more readily apparent by referring to the following detailed description and the appended drawings in which: FIG. 1 is block diagram of the invented secure teleprocessing bidding system. FIG. 2 is a sample bid document produced by the invented secure teleprocessing bidding system. FIG. 3 is a mutually exclusive bid comparison report produced by the secure teleprocessing bidding system. FIG. 4 is a bidder work sheet for the secure teleprocessing bidding system. FIGS. 5 through 8 are a flow chart of the preferred embodiment of the invented system. FIG. 9 is a sample file format for the invented system. DETAILED DESCRIPTION In its preferred embodiment, the invention provides an alternative to the contractor/subcontractor bidding system as it now exists while retaining the structure of the system. The invented system keeps track of several projects, each having several general contractors bidding for the right to do the construction. Each project has several predefined divisions of work for which subcontractors submit bids to each relevant general contractor for the right to perform the work described in a division. The invented system provides a simplified method for the submission of bids to several general contractors, each bidding on a single project. Referring now to the drawings, and particularly to FIG. 1, the invented secure teleprocessing bidding system includes a PC computer system 6 provided with a fax card 9, a modem 14, speech synthesizer 11, speech-to-text converter 24, clock 12, keyboard 8, monitor 7, and printer 15. Access to the system is provided via a PBX telephone system 2 and/or a fax machine 16 connected to phone line 1. The PBX unit can also provide access to a roll over secondary unit 19 if the primary unit is occupied. A tape recorder 3 provides an audio backup of the transactions as well as an audit trail. Finally, an optional human operator 5 listening via headphones 4 is provided for. The secure teleprocessing bidding system provides a transaction processing system, wherein each bid is related to a specified bid recipient, i.e., the general contractor, for a specified division in a specified project. To provide an audit trail, both a tape recording and an electronic recording can be made of each transaction. To initiate the process, the bidder, i.e. the subcontractor, fills out a work sheet similar to that shown in FIG. 4. The bidder then enters this transaction into the system via modem, fax, or a voice phone call. As such bids are currently entered via phone, in the preferred embodiment the bidder phones the system and is routed via PBX 2 into the secure teleprocessing bidding system. While a speech-to-text converter 24 can be used to eliminate the human element 5 of this system, such converters can produce inconsistent results due to variants in individual speech patterns. Therefore in the preferred embodiment a human operator 5 listens to the transaction via headphone 4, and performs the data entry on keyboard 8 for the system. In order to provide maximum security in a situation where the human element is present, the operator should be unable to speak to the bidder, thus the PC computer 6 is programmed to provide the necessary prompts via speech synthesizer 11. In such an embodiment the human operator is acting merely as a translator or speech-to-text converter for the PC computer. This function can also be performed by the bidder by keying in his transaction on the telephone keypad in the situation where the bidder is more technically oriented. Prior to receiving bids, the system is set up to identify the various projects, divisions, bidders and bid recipients. Various file formats can be used to construct the software for use with the system. A sample format is shown in FIG. 6 for use with any of several off-the-shelf relational database products. Referring to FIGS. 5 through 8, as soon as the bidder has gained access to the system via PBX (see Block 100) the PC computer creates a transaction record (Block 101) placing the time and date into the relevant field and starts to record the transaction via tape recorder 3. Next the bidder file is opened (Block 101) in preparation for validation. The user is then prompted (Block 102) via the speech synthesizer to speak his bidder security number (SBN). At this point the human operator enters via keyboard 8 the security number spoken by the bidder (Block 103). The PC computer attempts to match this against its list of valid SBN's contained in the bidder file (Block 104). The bidder is given two opportunities to provide a valid bidder security number (loop: 106, 109, 112, 115). In the event the bidder is unable to provide a valid security number, the PC computer informs the bidder of impending termination (Block 107) and disconnects the call deleting the transaction file (Block 110). Upon the entry of a valid bidder security number, the appropriate bidder record is retrieved (Block 105) and information from the bidder's individual record is cross-referenced to the transaction file (Block 108). Next the bidder file is closed and the project file is opened (Block 114). At this point the PC computer prompts the bidder for the appropriate project and division number (Block 116). The bidder is then given several opportunities to provide a correct project and division number (Loop: 117, 201, 203, 205, 208). Upon receiving a valid project division number, the computer opens the project division list (Block 202). This file is the staging file from which the bids from all the bidders of a certain trade (division) are matched to all the bid recipients for a particular project and division, and are accumulated for formatting and processing. A bid recipient list is created (Block 204) containing all of the bid recipients for the division of the project on which the bidder wishes to bid. The bidder is prompted for a predominate bid amount (PBA) (Block 207). The predominate bid amount is the amount that the bidder intends to submit to a majority of the bid recipients. Once received, this amount is written into the transaction record (Block 213). The computer then inquires whether or not this amount is to be submitted to all of the bid recipients (Block 215). Upon receiving a response of yes, the bidder is presented with a disconnect message (Block 401) and the telephone connection is terminated (Block 402). At this stage the tape recorder is turned off and the recording is saved as a backup. The transaction is now posted into individual bid records and cross-referenced to the appropriate project and division along with each bid recipient's entry in the bid recipient file (Loop: 403, 404, 406, 410). After the PBA is posted any open file is closed (Block 405). A hard copy of the transaction file is then printed (Block 407). Finally the system is reset for the next caller. If the bidder answers no to the prompt, the computer locates each bid recipient in turn and inquires whether or not the bidder wishes the predominate bid amount to be submitted to the current recipient (Block 304). At each individual prompt, if the bidder says yes the predominate bid amount contained in the transaction file is written into a bid record and cross-referenced to that bid recipient, project and division files (Block 311). Should the bidder say no, he is prompted for the amount which is then written into a bid record and cross-referenced to the bid recipient, project and division files (Blocks 310, 312, 313). Upon reaching the last bid recipient, the computer signals that the transaction is complete (Block 302), disconnects the phone, stops the tape recorder, and closes any open files (Block 305). A hard copy of the transaction file is then printed (Block 307). At this point, no matter which path was taken, the computer saves the transaction file and reverts to the ready mode. The hard copy of the transaction is forwarded to the bidder to confirm his actions. After the deadline for receiving the bids for a particular project, a sort of the bid recipient numbers, the project/division numbers, and bid amounts is performed for each division in the project/division file. This sort can be performed by a variety of well known algorithms. Based on the sorted data a bid document is prepared and formatted, see FIG. 2. This document is saved both in hard copy and electronically to provide an audit trail. Then based on the bid recipient's preference, this document is either mailed, sent by modem or faxed to his office. After the bid recipient has given his consent to the release of bid information, the computer system produces a comparison report (FIG. 3) for the bidders which preserves bidder identity. Then based on the bidder's preferences these documents are either mailed, faxed, or uploaded, allowing the bidders to compare their bids with the bids of other bidders. ALTERNATIVE EMBODIMENTS While the above described system utilizes a human operator in its preferred mode, it should be recognized that this system could be entirely contained within one computer. Such a system would utilize a fax/modem board with an electronic digital mail system whereby a bidder can either submit information, as before, directly to the computer equipped with synthesizer to produce a response, or the bidder can type his bid information in via touch-tone phones. A bidder could also submit his information, on a standardized form, via the fax which would be digitized and analyzed by the computer to produce the transaction file, or, similarly, the system could accept information directly via modem from another computer. After the bidder provides his security number and the project and division number the system could perform a check to determine whether the bidder has already entered a bid for that division and terminate the transaction if such a bid exists. During the report providing stage, reports could be either faxed to the recipient, uploaded into the recipient's computer, posted to a electronic bulletin board system, or a phone call could be initiated by the computer and a report issued verbally via speech synthesizer. It is to be understood that the foregoing description and specific embodiments are merely illustrative of the best mode of the invention and the principles thereof, and that various modifications and additions may be made to the system by those skilled in the art, without departing from the spirit and scope of this invention, which is therefore understood to be limited only by the scope of the appended claims.
