Description of the Prior Art:
Increasing security problems are becoming a noticeable part of modern life, security was once primarily the preserve of classified government installations, but increasing losses and calamities have forces the review of security equipment and procedures by government and industry. Cargo losses and the theft of corporate secrets cost industry billions of dollars annually. Unauthorized access to computer data bases and other files are a major concern today and in the future. Public safety is endangered by the ability of intruders to plant bombs in places such as aircraft and buildings. Computerized records and even the computers themselves, are attacked and destroyed.
Access control and personnel identification are becoming tremendous problems, and will be the object of significant expenditures by organizations needing to identify employees, vendors, etc., who are to be allowed access to plants, computer rooms, vaults, baggage areas, etc. The ultimate method of personal identification s W O 97/21187 PCT~US95/15703 not a card which can be lost, loaned or stolen, nor a num~er code which can be told or purloined, but an unchangeable, non-transfera~le and indisputably unique characteristic of the person himself, his fingerprint.
With crime in the United States and elsewhere on the upswing and with the relative supply of trained law enforcement personnel on the decline, the law enforcement community has been forced, in recent years, to investigate and consider the automatic processing of the large amounts of data it is required to maintain.
One area of recent interest has been in the automatic processing of fingerprints. A few facts will serve to indicate why this is the case. The Federal Bureau of Investigation has a fingerprint file which consists of over 182,000,000 fingerprint cards, each having 10 prints thereon. There are some 13,00Q agencies throughout the world contributing ~ingerprint cards to the FBI and the FBI receives over 27,500 inquiries per day. In its Washington offices alone, the FBI has over 1000 people whose task it is to search and classify fingerprint cards. The California Bureau of Cr;~inAl Identification and Investigation has a file consisting of approximately 5,500,000 fingerprint cards and receives in excess of 95,000 inquiries per month. The New York State Identi~ication and Intelligence System has a file in excess of 1,300 r ~~~ fingerprint cards and receives more than 200,000 inquiries per year. These W O 97/21187 PCT~US95115703 figures alone serve to indicate the enormity of the task of reading and classifying fingerprints for the purposes of ide~tification and matching.
Other areas would benefit from a device for automatically reading fingerprints. For example, the economy of the United States today is based on the credit system and the use of credit cards. However, millions of dollars are lost annually because of the use of lost or stolen credit cards. With an automatic fin~erprint reader and correlator, much of this could be eli m; n~ted, Each credit card could be made so that upon insertion into a machine, a central storage file would automatically locate the file of the credit cared owner which would include his or her fingerprint records.
Then, by merely placing the credit card holder's finger on a glass or the like, an automatic reader could read the fingerprint and provide the information to a correlation system which would determine whether the fingerprint of the credit card holder matches those in the file of the credit card owner. With automatic reading and correlating apparatus, this could be done in a matter of seconds.
Because of the importance of this problem, many suggestions have been made in recent years for automatic fingerprint readers and recorders. Many of the proposed systems operate to locate fingerprint minutiae, such as ridge endings or bifurcations, since the use of W O 97/21187 PCT~US95/15703 fingerprint minutiae as a means of positive, legal identification has been proven in practice. Therefore, since the automatic detection of specified minutiae is ~ basically a problem in pattern recognition, it would appear to be a simple matter to provide an automatic system of the detection of such minutiae. However, the recognition of these minutiae is complicated by several factors, such as: (1) the specified minutiae occur at arbitrary orientations; (2~ there are variations in ridge breadth and distance between ridge centers; (3) there are various inherent defects in all fingerprints, such as scars, warts, etc.; ~4) false ridge endings appear at the boundaries of fingerprints and scars; and (5~ the quality of fingerprints varies widely with respect to contrast and clarity. As a result, in almost all cases, the proposed system has either been too complex, too inefficient or inoperative.
For example, it has been proposed to use a large scale computer to control the scan of a fingerprint along some predetermined pattern and so store the resulting complex electrical signal. Subsequently, in order to identify a fingerprint, it will have to be scanned and the resultant complex electrical signal compared with those in the memory banks of the computer.
Although this approach may well be operative r it has the inherent disadvantage of all mass data-processing W O 97/21187 PCTnJS95/15703 systems, and that is the requirement for enormous amounts of complex and costly e~uipment.
Another suggested approach has been to use holographic techniques whereby two fingerprints may be matched or the location of specified minutiae on fingerprints identified by simultaneously illuminating an unknown fingerprint and a known mask with coherent laser light and determ;n;ng the locations of a match.
However, apparently because of the complexity and the minute detail present in typical fingerprints, it has not been possible to make such a system which operates reliably.
The American economy, over the years in the 2Oth Century, has slowly but surely changed into an economy centered on credit. As a business man travels from his banks to department stores to gas stations to restaurants, the credit card that is acceptable at each one of those institutions is di~ferent in most cases from the other cards that he must carry. As a business person travels throughout this country, from state to state, or throughout the world, from country to country, he or she is more and more burdened by the large number of various types and styles of credit cards that he must carry with him.
It is known to carry credit cards that are backed by large banking organizations. Cards such as a Visa or MasterCard are but two of the examples of this modern form of credit card. Although these cards are useful in a wide variety of situations, for example purchasing goods at a store or lodging at a hotel or ~ inn, it is not uncommon for a single individual to have three or four of each of these types, each being issued by a different bank.
Another problem that may exist is when a card is ~irst issued, a small figure, for example $500 or $600, is established as a line of credit. However, as time proceeds and the individual proves to be a good credit risk, that line of credit is ~p~n~d to an amount $2,000 to $5,000. It is very o~ten di~ficult, when one person has four or five Visas or MasterCards, for that person to remember what credit limit applies to which card. More times than not, for a particularly large purchase, an individual might at first try to use a card that does not have sufficient credit on it, to the embarrassment of the card holder, even though he does have two or three other cards that do have su~ficient credit on them.
Even though a person can get a bank credit card, this does not preclude the use of three or four cards from typically local establishments. While in the most part these establishments are department stores, and usually very large department stores at that, they are regional in their use. Therefore, a person traveling from the East Coast to the West Coast would find that he CA 02239627 l998-06-04 W O 97/21187 PCT~US95/15703 or she could no longer make purchases in a well-known department store on the West Coast because his credit reputation is known only to the East Coast department stores .
Plastic cards have gained great popularity in recent years as a medium by which purchase money is paid and business transacted without the necessity of carrying cash or enduring a long term escrow or other means for transferring title or securing payment of cash. With the popularity and ready acceptance of credit cards in the business world, the use thereof by unscrupulous persons to make unauthorized transaction has become a serious problem costing the consumers millions of dollars annually. As the ~e~n~ for such cards has risen amongst counterfeiters and other illegal uses, the demand for improperly obtained cards market has skyrocketed thus creating an extremely high incentive for dishonest employees connected with the manufacture of such cards to succumb to temptation. Such employees are presented daily with a temptation to supply cards to persons bent on improper use thereof, all for great sums of money.
There have been many e~forts in the past to assure the security of credit cards, including coding thereof for check at the point of purchase to determine if the card may be a stolen card. Other efforts have led to the construction of credit cards with a hologram strip secured to the face thereof and incorporating optical W O 97/21187 PCT~US95/15703 images characteristic of the particular card such that a merchant or other person to whom the card is presented will have an opportunity to ~ mi ne the card to determine if the hologram is in position and to identify the characteristics of the images incorporated therein.
While many efforts have been made to provide security against illegitimate use of stolen credit cards, little effort has been made, and even less success achieved, to provide security at the place of manufacture and storage of such cards prior to distribution to the end user. Consequently, there exists a need for a method of manufacture and a credit card which discourages theft by employees yielding to the temptation to supply such cards to others or to use the cards themselves for illegitimate purposes.
By way of background, counterfeiting of credit cards at the present time is relatively easy and can be accomplished effectively by unsophisticated counterfeiters. In this respect, the ordinary credit card is fabricated from a 20 mil core layer of polyvinyl chloride which is printed to provide information on the front and rear of the card. T.~m; n~ted to each of these layers is a 5 mil clear polyvinyl chloride sheet through which the printing can be seen. The total thic~ness of the card is 30 mils and it can be fabricated by the use of commercially available material. Thus, counterfeiters can obtain the basic materials for making a credit card W O 97/21187 PCT~US95/1~703 from normal commercial channels, and with a m;n;~l~ of equipment, may duplicate credit cards. It is with overcoming the foregoing ease of counterfeiting that the present invention is concerned.

The present system can be used to detect any type of minutiae such as ridge endings and~or bifurcations, as required. The system will detect as many specified minutiae as possible with a m; n;mllm number of false alarms.
Briefly, the present fingerprint minutiae reading device operates by sequentially observing small portions of a fingerprint, with the use of a flying spot scanner, to derive, at each position, an electrical analog signal indicative of the pattern at the position. The analog signal, so derived is converted into digital form and temporarily stored in a small memory having a plurality of storage elements. The signal in the memory is constantly circulated through each of the storage elements to aid in the recognition of minutiae regardless of their angular orientation. Finally, the occurrence of specified minutiae is detected by sensing the states of selected ones of the storage elements. An automatic contract control circuit adjusts the detection process as a function of the local quality of the fingerprint image to increase the probability of detection of minutiae in prints of relatively poor quality. The system includes apparatus to inhibit the recognition of false ridge endings in broken ridges, the ter~;n~tions of ridges at the print boundaries, or the term;nAtion of ridges produced by scars, and, if it becomes desirable to recognize the existence of scars, etc., the ridge endings produced by scars may be detected and recorded for later processing.

Description of the Prior Art:
Increasing security problems are becoming a noticeable part of modern life, security was once primarily the preserve of classified government installations, but increasing losses and calamities have forces the review of security equipment and procedures by government and industry. Cargo losses and the theft of corporate secrets cost industry billions of dollars annually. Unauthorized access to computer data bases and other files are a major concern today and in the future. Public safety is endangered by the ability of intruders to plant bombs in places such as aircraft and buildings. Computerized records and even the computers themselves, are attacked and destroyed.
Access control and personnel identification are becoming tremendous problems, and will be the object of significant expenditures by organizations needing to identify employees, vendors, etc., who are to be allowed access to plants, computer rooms, vaults, baggage areas, etc. The ultimate method of personal identification s W O 97/21187 PCT~US95/15703 not a card which can be lost, loaned or stolen, nor a num~er code which can be told or purloined, but an unchangeable, non-transfera~le and indisputably unique characteristic of the person himself, his fingerprint.
With crime in the United States and elsewhere on the upswing and with the relative supply of trained law enforcement personnel on the decline, the law enforcement community has been forced, in recent years, to investigate and consider the automatic processing of the large amounts of data it is required to maintain.
One area of recent interest has been in the automatic processing of fingerprints. A few facts will serve to indicate why this is the case. The Federal Bureau of Investigation has a fingerprint file which consists of over 182,000,000 fingerprint cards, each having 10 prints thereon. There are some 13,00Q agencies throughout the world contributing ~ingerprint cards to the FBI and the FBI receives over 27,500 inquiries per day. In its Washington offices alone, the FBI has over 1000 people whose task it is to search and classify fingerprint cards. The California Bureau of Cr;~inAl Identification and Investigation has a file consisting of approximately 5,500,000 fingerprint cards and receives in excess of 95,000 inquiries per month. The New York State Identi~ication and Intelligence System has a file in excess of 1,300 r ~~~ fingerprint cards and receives more than 200,000 inquiries per year. These W O 97/21187 PCT~US95115703 figures alone serve to indicate the enormity of the task of reading and classifying fingerprints for the purposes of ide~tification and matching.
Other areas would benefit from a device for automatically reading fingerprints. For example, the economy of the United States today is based on the credit system and the use of credit cards. However, millions of dollars are lost annually because of the use of lost or stolen credit cards. With an automatic fin~erprint reader and correlator, much of this could be eli m; n~ted, Each credit card could be made so that upon insertion into a machine, a central storage file would automatically locate the file of the credit cared owner which would include his or her fingerprint records.
Then, by merely placing the credit card holder's finger on a glass or the like, an automatic reader could read the fingerprint and provide the information to a correlation system which would determine whether the fingerprint of the credit card holder matches those in the file of the credit card owner. With automatic reading and correlating apparatus, this could be done in a matter of seconds.
Because of the importance of this problem, many suggestions have been made in recent years for automatic fingerprint readers and recorders. Many of the proposed systems operate to locate fingerprint minutiae, such as ridge endings or bifurcations, since the use of W O 97/21187 PCT~US95/15703 fingerprint minutiae as a means of positive, legal identification has been proven in practice. Therefore, since the automatic detection of specified minutiae is ~ basically a problem in pattern recognition, it would appear to be a simple matter to provide an automatic system of the detection of such minutiae. However, the recognition of these minutiae is complicated by several factors, such as: (1) the specified minutiae occur at arbitrary orientations; (2~ there are variations in ridge breadth and distance between ridge centers; (3) there are various inherent defects in all fingerprints, such as scars, warts, etc.; ~4) false ridge endings appear at the boundaries of fingerprints and scars; and (5~ the quality of fingerprints varies widely with respect to contrast and clarity. As a result, in almost all cases, the proposed system has either been too complex, too inefficient or inoperative.
For example, it has been proposed to use a large scale computer to control the scan of a fingerprint along some predetermined pattern and so store the resulting complex electrical signal. Subsequently, in order to identify a fingerprint, it will have to be scanned and the resultant complex electrical signal compared with those in the memory banks of the computer.
Although this approach may well be operative r it has the inherent disadvantage of all mass data-processing W O 97/21187 PCTnJS95/15703 systems, and that is the requirement for enormous amounts of complex and costly e~uipment.
Another suggested approach has been to use holographic techniques whereby two fingerprints may be matched or the location of specified minutiae on fingerprints identified by simultaneously illuminating an unknown fingerprint and a known mask with coherent laser light and determ;n;ng the locations of a match.
However, apparently because of the complexity and the minute detail present in typical fingerprints, it has not been possible to make such a system which operates reliably.
The American economy, over the years in the 2Oth Century, has slowly but surely changed into an economy centered on credit. As a business man travels from his banks to department stores to gas stations to restaurants, the credit card that is acceptable at each one of those institutions is di~ferent in most cases from the other cards that he must carry. As a business person travels throughout this country, from state to state, or throughout the world, from country to country, he or she is more and more burdened by the large number of various types and styles of credit cards that he must carry with him.
It is known to carry credit cards that are backed by large banking organizations. Cards such as a Visa or MasterCard are but two of the examples of this modern form of credit card. Although these cards are useful in a wide variety of situations, for example purchasing goods at a store or lodging at a hotel or ~ inn, it is not uncommon for a single individual to have three or four of each of these types, each being issued by a different bank.
Another problem that may exist is when a card is ~irst issued, a small figure, for example $500 or $600, is established as a line of credit. However, as time proceeds and the individual proves to be a good credit risk, that line of credit is ~p~n~d to an amount $2,000 to $5,000. It is very o~ten di~ficult, when one person has four or five Visas or MasterCards, for that person to remember what credit limit applies to which card. More times than not, for a particularly large purchase, an individual might at first try to use a card that does not have sufficient credit on it, to the embarrassment of the card holder, even though he does have two or three other cards that do have su~ficient credit on them.
Even though a person can get a bank credit card, this does not preclude the use of three or four cards from typically local establishments. While in the most part these establishments are department stores, and usually very large department stores at that, they are regional in their use. Therefore, a person traveling from the East Coast to the West Coast would find that he CA 02239627 l998-06-04 W O 97/21187 PCT~US95/15703 or she could no longer make purchases in a well-known department store on the West Coast because his credit reputation is known only to the East Coast department stores .
Plastic cards have gained great popularity in recent years as a medium by which purchase money is paid and business transacted without the necessity of carrying cash or enduring a long term escrow or other means for transferring title or securing payment of cash. With the popularity and ready acceptance of credit cards in the business world, the use thereof by unscrupulous persons to make unauthorized transaction has become a serious problem costing the consumers millions of dollars annually. As the ~e~n~ for such cards has risen amongst counterfeiters and other illegal uses, the demand for improperly obtained cards market has skyrocketed thus creating an extremely high incentive for dishonest employees connected with the manufacture of such cards to succumb to temptation. Such employees are presented daily with a temptation to supply cards to persons bent on improper use thereof, all for great sums of money.
There have been many e~forts in the past to assure the security of credit cards, including coding thereof for check at the point of purchase to determine if the card may be a stolen card. Other efforts have led to the construction of credit cards with a hologram strip secured to the face thereof and incorporating optical W O 97/21187 PCT~US95/15703 images characteristic of the particular card such that a merchant or other person to whom the card is presented will have an opportunity to ~ mi ne the card to determine if the hologram is in position and to identify the characteristics of the images incorporated therein.
While many efforts have been made to provide security against illegitimate use of stolen credit cards, little effort has been made, and even less success achieved, to provide security at the place of manufacture and storage of such cards prior to distribution to the end user. Consequently, there exists a need for a method of manufacture and a credit card which discourages theft by employees yielding to the temptation to supply such cards to others or to use the cards themselves for illegitimate purposes.
By way of background, counterfeiting of credit cards at the present time is relatively easy and can be accomplished effectively by unsophisticated counterfeiters. In this respect, the ordinary credit card is fabricated from a 20 mil core layer of polyvinyl chloride which is printed to provide information on the front and rear of the card. T.~m; n~ted to each of these layers is a 5 mil clear polyvinyl chloride sheet through which the printing can be seen. The total thic~ness of the card is 30 mils and it can be fabricated by the use of commercially available material. Thus, counterfeiters can obtain the basic materials for making a credit card W O 97/21187 PCT~US95/1~703 from normal commercial channels, and with a m;n;~l~ of equipment, may duplicate credit cards. It is with overcoming the foregoing ease of counterfeiting that the present invention is concerned.
