Description
-1- Method and Device for the Identification and Recognition of Living Beings and/or Objects The invention concerns a method and a device for the identification and recognition of living beings and/or objects.
Methods and apparatus of this type are in wide spread use for situations e.g.
in which the identity of a person must be determined e.g. to authorize access or entrance. Examples thereof are banking machines, computer work locations, entrance to companies, security areas or lockers. Methods and devices are known in the art with which identification papers, chip cards, with or without personal identification numbers (PIN), or passwords are used.
These conventional methods and devices have the disadvantage that a special medium must always be carried along with the person for his identification. In 15 the event that this medium is forgotten, access or entrance is not possible. In
I
the event that the medium is taken by a non-authorized person, this individual can gain access or entrance. The conventional methods are therefore difficult ii o.
S for the user and are not reliable with respect to their operation.
•llll= 20 Additional methods and devices are known in the art (US 5 067 162) with which the identification of a person is based on fingerprinting techniques. An image is taken of the skin lines of the finger of a person to be identified and stored. An additional image is prepared for recognition of the corresponding person and is directly compared to the first stored image. In the event that the images agree, the person is identified. This procedure has the disadvantage that the direct comparison between the two images required by the examination procedures is relatively burdensome. As a result, the comparison takes some time and requires a large amount of memory in the computer carrying out the method. In addition, the recognition or identification of a person is not successful if the skin lines have changed, e.g. due to an injury.
02/02/01,td 10580.spe, 1 -2- According to a first aspect of the invention there is provided a method for the identification and recognition of living beings and/or objects, wherein a reference image is created in which a predetermined section of the living being to be identified or of the object to be identified is recorded by an image recording apparatus, and with which a reference data set is created in which characteristic features and their positions are extracted from the reference image and stored with the assistance of a computer and with the assistance of software for numerical methods, wherein the living being or the object is identified by recording an identification image of the predetermined section with the assistance of an image recording apparatus, and the identification image is investigated for the presence of the data in the reference data set with the assistance of a computer which runs numerical methods software.
According to a second aspect of the invention there is provided a device for 15 identification and recognition of living beings and/or objects, in particular for 0 06 carrying out the method in accordance with the previously defined method, characterized by the following features: a first image apparatus is provided for taking a reference image of a 20 predetermined section of the living being to be identified or of the object to be identified a first computer and a first computer program are provided far determining characteristic features and their positions in the reference image, a memory medium is provided for storing the characteristic features add their positions as a reference data set, a second image recording apparatus is provided for identifying the living being or the object which records an identification image of the predetermined section, and a second computer and a second computer program are provided for checking A~ he identification image for the presence of the data of the reference data set.
05/02/01 ,td10580.spe,2 2a The invention has the advantage that a reference image is first created in which a predetermined section of the living being to be identified or of the object to be identified is recorded by an image recording apparatus.
Characteristic features and their pbsitions are subsequently extracted from this reference image and stored as a reference data set in a storage unit. In order to identify or recognize the living being or the object, an identification image is recorded of the predetermined section with the assistance of an image recording device. The identification image is subsequently examined for the presence of the features and positions of the reference data set. In the event that these features are only present at the predetermined positions in the identification image, the corresponding person or object is considered to be identified. If however the features are not present or are located in other positions, the living being or object is considered unidentified. Depending on 15 the application, the number of features stored in the reference status set can differ. It depends upon the complexity of the recorded structures of the living being or object to be .o °ego• *o* oooo •oo* 02/02/01 ,td 10580.spe,2 11 It 3 identified, on the desired precision of the identification, and on the features of the image recording apparatus. The method in accordance with the invention and the device in accordance with the invention operate rapidly and reliably, since the amount of data to be stored is small and there is no direct comparison between the reference image and the identification image, rather only the data in the reference data set are sought in the identification image. The identification procedure is therefore rapid and does not require increased memory or storage capacity. Portions of the corresponding living being which are suitable for identification or of the corresponding object are e.g.
portions of the surface of the object or special skin portions of the living being. In the case of a human being, this can e.g. be the finger or the face, since these are rarely covered by clothing and therefore are always available for inspection purposes.
In accordance with an advantageous configuration of the method in accordance with the invention, the relative positions of the features are determined and stored in the reference status set. The origin of the associated reference system can thereby e.g. be located in the position of one of the features. This simplifies location of the features in the identification image.
In accordance with an additional advantageous configuration of the method in accordance with the invention, patterns or regularities present in the section are utilized for identification of the living being or of the object. In this manner, living beings even having small injuries or deformations in portions of their bodies or objects having a _small degree of damage can be identified and recognized.
4 In accordance with an additional advantageous configuration of the method in accordance with the invention, the reference data set is adapted to differences in the features and their positions. In this manner, chronic changes in people or constant changes in objects can be taken into account. A corresponding examination of the reference data set can be carried out for each identification procedure.
In accordance with an additional advantageous configuration of the method in accordance with the invention, a plurality of differing types of features are utilized for the reference data set. If, for example, the section to be identified is the finger of the person, e.g. topological or morphological structures can be utilized as features. These include e.g.
skin lines or glands, such as the sebaceous gland or the perspiratory gland. The utilization of a plurality of different types of features increases the reliability of the method, particularly when the identification of sections changed, with regard to certain features, by damage or injury.
In accordance with an additional advantageous configuration of the method in accordance with the invention, a plurality of features are transformed into numerical values and collected together into one value. In this fashion, the amount of data can be reduced and the identification procedure accelerated.
In accordance with an additional advantageous configuration of the method in accordance with the invention, a plurality of features of a certain type are collected into a pattern or a pattern group. In this manner, a plurality of people or objects can be investigated for agreeing features and subdivided into groups.
In accordance with an additional advantageous configuration of the method in accordance with the invention, additional data (personal identification number, data on a data storage medium) are entered to provide assistance for searching the reference data set in the memory. This additionally accelerates the identification process.
In accordance with an additional advantageous configuration of the method in accordance with the invention, a plurality of differing numerical methods are utilized, possibly simultaneously, to generate the reference data set and to identify the living being or object. This facilitates high flexibility and speed for the method and the device. In addition, the influencing, falsification or copying of the method or the device is rendered more difficult to thereby increase reliability and security.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the Trelly method is used, in addition to other numerical methods, to produce the reference status set and to identify the living being or object.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the Wavelet method is utilized, in addition to other numerical methods, to produce the reference data set and to search for the features of the reference data set in the identification image. This procedure thereby facilitates data compression, combining of images, reconstruction of imaging errors, the recognition and selection of features, as well as utilization of the fact that phase information is communicated. In addition, possibilities are provided for increasing the processing speed and reducing the amount of data.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the living being to be identified is a person.
In accordance with an additional advantageous configuration of the method in accordance with the invention, characteristic parts 6f the epidermis are utilized as features for individualized identification of the person.
These include e.g. skin lines, perspiratory and sebaceous glands as well as their openings, vessels, in particular blood vessels, as well as their pulsing motion. It is thereby particularly advantageous to indicate the position of the gland openings relative to the skin lines. In the event of time resolved recording, dynamic effects can also be registered, such as pumping or flowing motion or changes in diameter of the vessels, and used for identification.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the section of the person to be identified is the side of the finger opposite the finger nail. This side of the finger is also used in the conventional method of fingerprinting to record fingerprints and for their evaluation. However, in contrast to the conventional fingerprinting method, in accordance with the invention not only the features of the skin lines are recorded and evaluated rather also additional structures present on the epidermis such as perspiratory or sebaceous glands or vessels. In the event that image recording apparatus having an associated high degree of sensitivity are utilized, small structures such as glands or vessels or even structures below the surface of the skin can also be recognized and utilized for identification. The procedure can also involve the recording and evaluation of a plurality of fingers. In this manner, the recognition rate can be increased. In addition, in the event that one finger is injured, the remaining fingers are available for identification. Moreover, differing fingers can express differing intentions of the person.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the section of the person to be identified is the face or portions of the face. The characteristic features can thereby be properties of the epidermis or the position or color of the eyes, the position of the nose, the shape of the mouth, the position of the skin folds, or the shape of the face.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the natural thermal radiation of the human body is recorded by the image recording apparatus to generate a reference image and to identify the person. The recording of the reference or identification image can be facilitated without any irradiation or illumination of the relevant body portion. It also functions in absolute darkness. Soiling, interferences or small injuries to the surface of the skin only influence the reference or identification image to a small extent.
Furthermore, the person being identified is not influenced by an additional illumination source. In this fashion the method and the apparatus are non-invasive in any physical sense.
In accordance with an additional advantageous configuration of the method in accordance with the invention, light in the visible or in the infrared wavelength region is utilized to generate the reference image and to identify the person. An additional light source to illuminate the relevant section is not necessary in particular when utilizing a sensitive image recording apparatus, since the environment always has sufficient ambient and scattering light. In this case as well, the person to be identified is not irradiated by an additional light source and does not experience any associated invasiveness.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the section of the person to be identified is illuminated with a light source in the visible or infrared wavelength region. To the extent that an additional illumination source is necessary for carrying out the method, same can be disposed directly in the apparatus or spatially separated therefrom, e.g. on the ceiling, walls or on the floor of the room in which the device in accordance with the invention is situated and the method in accordance with the invention is carried out. The illumination can also be selectively used for other purposes.
In addition, a directed temporal or geometric spatial control of the illumination is possible. For example, illumination may only occur when the recording device records an image.
In accordance with an additional advantageous configuration of the method in accordance with the invention, filters are utilized to filter out wavelength regions in conjunction with recording of the reference image and the identification image. For example, filters can be utilized in an image recording apparatus sensitive to infrared wavelength regions to filter out wavelength regions neighboring the infrared.
This can correspondingly be applied to image recording apparatus sensitive to visible light or to thermal radiation.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the recording of the reference image and of the identification image is effected without contact with the device containing the image recording apparatus. In this manner, the device does not experience soiling or prints which could influence the subsequent recording. To the extent necessary, a spacing device can be provided for specifying the separation between the section to be identified and the image recording apparatus.
In accordance with an additional advantageous configuration of the method in accordance with the invention, for recording the reference image or the identification image, the person to be identified is guided by optical or acoustical signals for precise positioning of the section relative to the image recording apparatus. In this manner, e.g. colored lamps or indicators having arrows can be provided for to show the user in which direction the relevant section should be displaced.
This can also be effected by an appropriate sound, a melody or a speech announcement. The focus of the image recorded by the image recording apparatus can be utilized to determine the distance. The information concerning the position having the correct separation (focussing) and centering within the image can then be determined from the extracted reference data. Light barriers or position measuring procedures can, however, also be utilized- In accordance with an additional advantageous configuration of the method in accordance with the invention, the reference image is converted into electrical signals, digitized and stored as reference data in a memory in the form of a data matrix.
\I\
In accordance with an additional advantageous configuration of the method in accordance with the invention, the reference data are stored in a central storage medium. In this manner, a plurality of systems or devices can simultaneously gain access to the reference data.
In accordance with an additional advantageous configuration of the method in accordance with the invention, the reference image is transformed into electrical signals, digitized and stored as reference data in an external data storage medium in the form of a data matrix. This can thereby be a chip card or a transponder. The associated person must carry the data storage medium with him for purposes of identification. The identification procedure is thereby more rapid, since the identification image of the person must only be compared to the reference data of the accompanying data storage medium.
Access to a central computer and the determination of the corresponding reference data set in the central memory is thereby not necessary. This type of external data storage medium carried along with a person to be identified is particularly suitable when there are a large number of people which are to be identified with the assistance of the method and the device. This could e.g. be the case for customers of a bank.
In accordance with an additional advantageous configuration of the invention in connection with a method for determining the authorization of a person to perform a certain task, the authorization of the person is determined with the assistance of the method in accordance with the invention through identification and recognition of the person. Towards this end, the method in accordance with the identification can be an integral part of the authorization check. Authorization can concern an access authorization or an entrance authorization. Such is the case e.g. for banking machines, personnel entrances or security regions. The identification of the person is used to grant authorization, e.g. to operate a particular apparatus or for opening a door. An authorized person can also pass additional authorizations on to third parties. Particular groups of people can be authorized for differing tasks so that a decision structure can be imparted to the system. Towards this end, the Petri network mechanism can be utilized. Authorizations can also be conjoined, distributed or revoked at a later time. The method can be integrated into a process control or monitoring language or into an instrumentation, data flow, or representation language. Examples thereof are the software tools of the company National Instruments such as Labview, Lab Windows, CVI or Bridgeview. The method can e.g. be used for purchasing, for the dispensing of cash, for access to a databank, or for entrance control purposes.
In accordance with an additional advantageous configuration of the invention, authorization can be spatially and/or time constrained. This is e.g. advantageous in the event that the relevant person is only located for a particular time at a particular location. This could e.g. be a hotel in which a person lives during a vacation or in a hospital or a sanatorium in which the person is staying for recuperative purposes. When the stay is ended, the issued authorizations can also be terminated and e.g. all invoices associated with the person can be issued. The external storage medium on which the reference data are stored can e.g. be integrated into a key used by the individual during the time of his stay, a pin or a badge. One can also provide that the reference data be deposited in a central storage medium or in a computer network so that no additional data storage medium is necessary for identification purposes. For search purposes
L
12 a personal identification number or other additional features could be used.
In accordance with an additional advantageous configuration of the invention, the authorization can be limited to a certain number of tasks. This number can, in particular, be different for differing people.
In accordance with an additional advantageous configuration of the invention, the method in accordance with the invention for identification of the person can be utilized to check whether or not the person has performed a task. This is e.g.
necessary for guard services.
In accordance with an additional advantageous configuration of the invention, the method in accordance with the invention is utilized for additional examination of electronic signatures. In this manner, e.g. the unique identification capability of the finger of a person can be utilized to identify the person. The method in accordance with the invention can be incorporated into a cryptological system with which individuals can be identified and the information associated with the person encoded and protected from changes. In particular, the method in accordance with the invention can be used to inspect the authorization of a person accessing the data.
The device in accordance with the invention for identification and recognition of a living being or an object has a first image recording apparatus to record a reference image of a predetermined section of the living being to be identified or of the object to be identified.
Characteristic features and their positions are determined in the reference image with the assistance of a first computer and a first computer program. These data are stored as a reference data set in a storage medium. A second image recording apparatus is used to record an identification image for identification of the living being or of the object.
A
second computer as well as a second computer program check the identification image for the presence of the data in the reference set. If these features are present in the identification image, the living being or the object is considered to be identified.
In accordance with an advantageous configuration of the device in accordance with the invention, an image recording apparatus is provided for which assumes the function of the first and the second image recording apparatus. In this manner, only one image recording apparatus is required for generating a reference data set and for identifying the person.
In accordance with an additional advantageous configuration of the device in accordance with the invention, a computer is provided for taking over the function of the first and the second computer. In this fashion, only one computer is required for generating the data set and for identifying the person or the object.
In accordance with an additional advantageous configuration of the device in accordance with the invention, the two image recording apparatus and the two computers can also be spatially separated from each other. This is particularly necessary when the reference data set is generated at a location different than that where the identification is performed.
