[0001] The present invention relates generally to the field of database maintenance and particularly to the field of attendance recorders. More particularly, present invention relates to smart attendance recorder that enables infection free recording of attendance using self-sanitization and thermal screening capabilities thereof.
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Undoubtedly, maintaining the record of attendance has always remained an unavoidable task for all types of workplaces. Earlier, representatives maintained attendance records by manually noting down the details such as entry time, exit time, date, and purpose of users entering a premise. The process of manually taking attendance was quite time-consuming and required manpower to be present explicitly therefor.
[0004] Gradually, with the growth of the technology, manual attendance recording was replaced by attendance recording machines based on the principle of biometric verification of users. Herein, biometric samples of all the relevant users (face, fingerprint, palmprint, iris and/or voice) are acquired by multiple sensors, stored to create a database of users to be verified later, and processed to verify the identity of users attempting to authenticate their identity. The attendance recorders mark the attendance of the users passing the verification test, else request reattempts.
[0005] Heretofore, many biometric attendance recorders have been envisioned. Unfortunately, all such attendance recorders require contact of users with the machine for acquiring biometric samples. Like, fingerprint recognition mandates the contact of fingerprints on the acquisition portion, thereby matching the fingerprints with those stored in the database to validate the identity of the requesting user. Similar is the case with palmprint recognition and some other biometric variants.
[0006] Moreover, biometric machines are usually optimized to equip touchscreen for user interaction. Users access the machine for different purposes by touching the screen of the attendance machine and thereby, making a contact. Since attendance machines facilitate such functionalities to multiple users, it is quite easy to spread infections, if present, from one user to another, thereby spreading communicable infections.
[0007] Several attempts have been made to utilize contactless face recognition and/or iris recognition for contactless attendance recording. Still, there are potential risks of transmission of infections from one user to another user due to close proximity made by all the users with biometric attendance recorders whilst marking attendance therein.
[0008] Hence, there is an unavoidable need to envision attendance recorders that are contactless in nature and incorporate features to prevent the spread of infection amongst users using such machines, thus ensuring the safety of users and spreading health-related awareness amongst them.
[0009] The principal object of the present invention is to overcome the disadvantages of the prior art.
[0010] An object of the present invention is to provide a self-sanitizing attendance recorder.
[0011] Another object of the present invention is to configure an additional feature of real-time temperature screening in attendance recorders.
[0012] Another object of the present invention is to facilitate multiple options for biometric verification.
[0013] Another object of the present invention is to provide an Vein ID based secure verification of attempting users.
[0014] Yet another object of the present invention is to provide an attendance recorder facilitating secure and contactless data verification and maintenance.
[0015] The foregoing and other objects, features, and advantages of the present invention will become readily apparent upon further review of the following detailed description of the preferred embodiment as illustrated in the accompanying drawings.
[0016] The present invention relates to an attendance recorder evolved to prevent the spreading of communicable infections by incorporating self-sanitization and temperature screening capabilities therein.
[0017] According to an embodiment of the present invention, an attendance recorder comprises an electronic enclosure, a first module mounted on the enclosure and configured to process facial samples of atleast one user received from a first set of sensors, a second module mounted on the enclosure and configured to process vein sample(s) of another or the same user received from a second set of sensors, a third module fitted on the enclosure and operable to calculate temperature of the users using a third set of sensors, a touchscreen mounted on the enclosure to enable interactive display of results obtained from the first module, second module and third module and a UV sanitization strip augmented behind both, the touchscreen and the second module, to ensure their self-sanitization.
[0018] According to an embodiment of present invention, the first module, the second module and the third module is preferably used to detect face images, finger vein images and indicate abnormal temperature ranges respectively.
[0019] According to an embodiment of present invention, the first set of sensors 106, the second set of sensors and the third set of sensors is electively chosen to be Infrared face detection sensors, Near Infrared light emitting diodes and Infrared thermal screening sensors respectively.
[0020] According to an embodiment of present disclosure, the attendance recorder further comprises an audio input unit and an audio output unit for facilitating speech recognition of the users.
[0021] According to an embodiment of present disclosure, the attendance recorder further comprises an Ethernet port adapted to allow data transmission to a multitude of local area networks.

This disclosure may however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the disclosure to those of ordinary skill in the art. Moreover, all statements herein reciting embodiments of the disclosure, as well as specific examples thereof, are intended to encompass both structural and functional equivalents thereof. Additionally, it is intended that such equivalents include both currently known equivalents as well as equivalents developed in the future (i.e., any elements developed that perform the same function, regardless of structure).
[0028] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[0029] In some embodiments, the numerical parameters set forth in the written description and attached claims are approximations that can vary depending upon the desired properties sought to be obtained by a particular embodiment. In some embodiments, the numerical parameters should be construed in light of the number of reported significant digits and by applying ordinary rounding techniques. Notwithstanding that the numerical ranges and parameters setting forth the broad scope of some embodiments of the invention are approximations, the numerical values set forth in the specific examples are reported as precisely as practicable. The numerical values presented in some embodiments of the invention may contain certain errors necessarily resulting from the standard deviation found in their respective testing measurements.
[0030] The present invention relates to an attendance recorder configured to perform temperature screening whilst pursuing contactless biometric user verification and conducts self-sanitization thereafter, thereby ensuring infection free attendance recording.
[0031] Referring to Figure 1, in an embodiment, an attendance recorder comprises of an electronic enclosure 102, a first module 104 mounted on the enclosure 102 that constitutes face recognition module, a first sent of sensors 106 in association with the face recognition module, that constitute Infra-Red (IR) face detection sensors, a second module 108 mounted on the enclosure 102 that is ideally vein recognition module, a second set of sensors 110 in association with the vein recognition module, that constitute Near Infrared Light Emitting diodes (NIR LEDs), a third module 112 operable for thermal screening using a third set of sensors ideally chosen to be Infra-Red (IR) thermal screening sensors, a touchscreen 114 mounted on the enclosure 102 and an Ultra-Violet (UV) sanitization strip 116.
[0032] It would be appreciated by a person skilled in the art, that though the foreseeing embodiments are disclosed as per their best mode, other alternative embodiments may be suitably used as a modification thereof. Like, biometric trait recognition process used in the present disclosure may be performed using, inter alia, fingerprint, palmprint, iris and gait. Further on, other modified forms of sensors may be used to replace the disclosed IR face detection 106 and thermal sensors for facial detection and thermal screening respectively, and NIR-LEDs 110 for vein detection.
[0033] In an embodiment, the process of facial recognition may be based on determining the shape and size of jaw, chin, shape and location of the eyes, eyebrows, nose, lips, and/or cheekbones. 2D facial scanners may be reading and recording the face geometries. The facial geometry may be transferred to a recording database in terms of points. Further, a comparison algorithm may be used to perform face matching and thereby determining results.
[0034] Procedurally, the face detection module 104 receives the input data in the form of facial images and picks-out different features from those images by implementing different algorithms. The extracted features may be set as a standard to extract differences between multiple faces. Successful and unsuccessful facial detection may be notified to users by the touchscreen 114,
[0035] It would be appreciated by a person skilled in the art that the features may be chosen from wrinkles, eyebrows, nose structures, but not limited thereto and several other variations are possible. Module 104 may be accompanied by IR sensors 106 that function as heat measuring and face-detecting sensors for enabling contactless facial detection of the user in proximity.
[0036] In an embodiment, the process of vein recognition 108 may either identify vascular patterns in the bank of hands or fingers. To identify patterns in hands, near-infrared rays generated from a bank of Light-Emitting Diodes (LEDs) 110 may be adapted to penetrate the skin of the back of a user's hand. Due to significant differences in absorbance of blood vessels and other tissues, the reflected near-infrared rays may produce an extracted vascular pattern. From the extracted vascular pattern, substantially feature-rich data such as vessel branching points, vessel thickness, and branching angels may be extracted and stored as a template.
[0037] Referring to Figure 2, the near-infrared rays generated from the bank of LEDs penetrate the finger or hand and may be absorbed by the blood vessels such that the areas in which the rays are absorbed (i.e., veins) appear as dark areas. The vein patterns created in this way may be digitized and compressed in order to register them as a template. The procedure does not involve any contact with the disclosed module. The digital imaging of veins is carried out by Non-Infrared Light Emitting Diodes (NIR-LEDs) 110 arranged in a definite array and Charged Coupled Device (CCD) cameras 128.
[0038] A record of vein image database is maintained by processing one or more images of the user, wherein such images chategorized by allotting a user specific Vein ID. This in turn ensures safe identification and secure authorization and proves to be propitious as far as security is concerned in this data driven world.
[0039] Additionally, the thermal screening module 112 mounted on enclosure 102 may use IR sensors to screen the temperature of the user's body. The notification about the user's body temperature and its deviation from the standard body temperature may be notified on the touchscreen 114, thereby warning the user of any possible health issues. Herein, the touchscreen 114 facilitates the notifications pertaining to all the aforementioned modules.
[0040] Referring now to Figure 3, the UV sanitization strip 116 is augmented behind the touchscreen 114 and the behind the screen ofvein detection module 108 in order to ensure continual self-sanitization by the attendance recorder. The strip may be layered between the gap of the applied offset between the touchscreen and the enclosure 102. Similarly, strip 116 may also be augmented between the gap of the applied offset between the vein acquisition screen and the module circuitry disposed therebelow. Ideally, the UV strip 116 performs sanitization after every user of the attendance recorder 100, thereby ensuring removal of any virus present on the touchscreen 114.
[0041] As indicated in figure 3 and figure 4 and according to some embodiments, an Audio input unit 118, Audio Output unit 120, USB port 124, Ethernet port 122 and an LED indicator 126 may be adapted on the enclosure. The audio input unit 118 and audio output unit 120 facilitates speech recognition of the users, preferably via a microphone and speaker respectively. The audio output port 120 may also work as an indicator of delivering sound upon feeding or authentication of data. Optionally, audio output port 120 may be used as a source of indication/warning to users. Multiple ways of feeding data may be provided by this fortunate inclusion of an audio recognition facility.
[0042] According to an embodiment, USB port 124 may be used to assist in firmware update of motherboard/microprocessor fitted in the attendance recorder 100. Additionally, Gigabit Ethernet 122 may allow data transmission to a multitude of Local Area Network (LAN) (system, server, or any storage device) or any server with a data rate of 1 Billion bits per second or more.
[0043] A person skilled in the art would appreciate the fact that many modifications of the aforementioned disclosure are possible. A secondary battery source may be functionalized when the system functions on stand-by mode, different colors indicators may be used to showcase different color according to the assigned functions taken at that point of time, a monthly report may be generated using the data extracted from the disclosed attendance recorder, such that the data may include but not limited to user's date of entry-exit, temperature, working days and no. of leaves and more.
[0044] Referring now to Figure 5, a flow chart explaining the process of biometric database creation and storage of multiple users 200 is illustrated, according to some embodiments of present invention. In an embodiment, camera and IR sensors 202 are used to capture the samples 204, followed by pre processing of the samples 206 is the reference format standardized for an attendance recorder database management system. The biometric feature of the subject under test is compared with the already existing images in the reference database 210. The subject under test is included in the reference database in case of an unsuccessful identification 208 and neglected as a duplicate action in case the subject is already found to be present in the reference database 212.
[0045] Referring now to Figure 6, a flow chart explaining the process of user verification and thereby attendance recording 300 is shown, according to some embodiments of present invention. In an embodiment, camera and IR sensors 302 are used to capture the samples 304, followed by pre-processing of the samples 306 is the reference format standardized for an attendance recorder database management system. The biometric feature of the subject under test is compared with the already existing images in the reference database 310. In case the features of the subject under test successfully match with the features of any of the images already present in the database, the test is found to be a "Successful Match" and the attendance is recorded 308. In case the features of the subject under test remains unsuccessful to be matched with the features of any of the images already present in the database, the test is found to be an "Unsuccessful Match" and an error is displayed to show denial of attendance recoding 312.
[0046] It should be apparent to those skilled in the art that many more modifications besides those already described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims. Moreover, in interpreting both the specification and the claims, all terms should be interpreted in the broadest possible manner consistent with the context. In particular, the terms "includes" and "including" should be interpreted as referring to elements, components, or steps in a non-exclusive manner, indicating that the referenced elements, components, or steps may be present, or utilized, or combined with other elements, components, or steps that are not expressly referenced. Where the specification claims refers to at least one of something selected from the group consisting of A, B, C .... and N, the text should be interpreted as requiring only one element from the group, not A plus N, or B plus N, etc. The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments.
