Description

CREDIT CARD HAVING IMPLANTED ONE-TIME PASSWORD

AUTHENTICATION DEVICE

Technical Field

[1] The present invention relates, in general, to a credit card and, more particularly, to a credit card having an implanted one-time password authentication device. Background Art

[2] The term 'One-Time Password (OTP) authentication' refers to a method of performing authentication using a new password every time, in which passwords are used one time and are not used again. This is to more securely protect private information from the risk of hacking, password disclosure or the like, which occurs due to the use of fixed passwords. OTP creation devices, having such an authentication function, are integrated with various authentication means, such as dedicated OTP creation devices, mobile OTPs for installing OTP creation programs in mobile phones or Personal Digital Assistants (PDAs), smartcards, or Universal Serial Bus (USB) devices, and are applied in various ways.

[3] As an example, 'Method of Creating and Authentication One-time Password Using

Smart Card and Smart Card Therefor' are disclosed in Korean Pat. No. 10-0548636 Here, the coupling relationship between an OTP authentication device and a smart card has not been described in detail. However, according to well-known technology, the synthetic resin portion of a card is cut away so as to correspond to the size of an authentication device, and the authentication device is bonded to the cut portion of the card using an adhesive agent.

[4] However, in the conventional technology, the authentication device must be bonded to a credit card using an adhesive agent, so that there are problems in that safe and secure bonding cannot be achieved, and in that the authentication device is easily separated from the credit card according to the use environment, that is, in an environment in which the air is humid, or in the case in which the credit card falls into liquid, such as water, or external force is applied to the credit card. Disclosure of Invention Technical Problem

[5] Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and the present invention is directed to provide a credit card having an implanted OTP authentication device, which is coupled with the

OTP authentication device using coupling means, such as rivets or screws, thus realizing safe and secure coupling.

Technical Solution [6] The present invention provides a credit card having an implanted OTP authentication device, including: a single sheet body formed by bonding a plurality of sheets; and an

OTP authentication device implanted to the cut portion of the sheet body. [7] In the credit card, the sheet body may be configured such that one or more coupling parts are provided in the cut portion so as to be exposed, and the authentication device may be provided with coupling depressions, which correspond to the coupling parts. [8] It is preferred that the coupling parts be mounted to respective surfaces of the cut portion of the sheet body. [9] Furthermore, it is preferred that the coupling parts be integrally formed to be mounted to respective surfaces of the cut portion of the sheet body. It is preferred that the coupling parts, which are integrally formed, have an L-shape. [10] Furthermore, the authentication device may be configured such that at least one of upper and lower parts of portions in which the coupling depressions are formed is separable. [11] In the above-described construction, each of the coupling parts may be configured such that a plurality of support holes, into which parts of the sheet body are inserted, are formed in the unexposed portion thereof. [12] In the credit card, the coupling parts may be configured such that a plurality of first coupling holes is formed in the exposed portions thereof, and the authentication device may be configured such that a plurality of second coupling holes is formed in the upper and lower surfaces of the authentication device so as to pass through the coupling depressions.

Advantageous Effects

[13] According to the credit card of the present invention, the authentication device is implanted to the sheet body, that is, using coupling means, such as rivets or screws, so that safe and secure coupling is achieved, unlike the conventional technology, with the result that there is no concern that the authentication device may be separated from the credit card even in a use environment in which the air is humid, or in the case in which the credit card falls into liquid, such as water, or external force is applied to the credit card.

Best Mode for Carrying Out the Invention

[21] A credit card having an implanted one-time password authentication device according to a preferred embodiment of the present invention is described in detail with reference to the accompanying drawings.

[22] As shown in FIG. 1, the credit card 100 according to the present embodiment includes a sheet body 110, which is provided with first, second and third sheets 111, 112 and 113 and upper and lower coating papers 114 and 115, and an OTP authentication device 120.

[23] The first, second and third sheets 111, 112 and 113 are formed thin using synthetic resin material, and are layered in the order shown in FIG.1.

[24] The upper and lower coating papers 114 and 115 are formed very thin using synthetic resin material. The upper coating paper 114 is located on the upper surface of the first sheet 111, but the lower coating paper 115 is located on the lower surface of the third sheet 113.

[25] The first, second and third sheets 111, 112 and 113 and the upper and lower coating papers 114 and 115, which are disposed in the above-described order, constitute a card having a predetermined thickness, for example, a thickness of about 0.82 mm.

[26] A corner of each of the first, second and third sheets 111, 112 and 113, having a predetermined area, and a corner of each of the upper and lower coating papers 114 and 115, having a predetermined area, are cut away.

[27] The OTP authentication device 120 is a device that creates and transmits an authentication code according to rules that are set in advance between a client, requesting authentication, and an authentication server, and is provided with a mechanism for acquiring authentication on the transmitted code through integrity verification. For the integrity verification, hash functions, such as MD4, MD5, RC4 and IEDA, are generally used. It is well known that an algorithm is generally selected according to the memory size and operation capability of a device.

[28] Generally, an OTP is mathematically based on a unidirectional function f(s), that is, a hash function, and is characterized in that an input value cannot be analogized from an output value. For example, in an s/key system (RFC1760), an OTP is created using the hash function F (s) based on an initial secret value, and then the created password is used again as a secret value for a new function. That is, the created password is used as follows: f(s), f(f(s)), f(f(f(s))). . ..

[29] The created password is decrypted by a user in the reverse order. In the case where an indefinite number of passwords are required, a new secret value s is repeatedly used for the creation thereof.

[30] OTP solutions, which are currently used, are classified into a time synchronization method, an event synchronization method, a query and response method, and a combination method according to password synchronization between a server and a client. In the time synchronization method, a current time, along with a secret key value, is used as the input of the hash function. In the even synchronization method, when an OTP is created, the number of times that a specific event occurs, such as the number of times that a user pushes a password generator, along with a secret value, is used as the input of the hash function. In the query and response method, a new password is created by inputting random numbers, which are provided by an authentication server or through a transaction process, to an OTP generator. In the combination method, both methods, that is, the time synchronization method and the even synchronization method, are used in order to make up for the drawbacks of the time synchronization method and the even synchronization method. Of the above-described methods, a method suitable for a use environment may be adopted for use thereof.

[31] The OTP authentication device 120 of the present embodiment may employ any device as long as the above-described mechanism is provided therein.

[32] As shown in FIG. 2, the OTP authentication device 120 is detachably coupled to the cut portion of the sheet body 110, which is formed in a single body by thermal bonding.

[33] First and second coupling parts 130a and 130b are provided in the cut portion. When the first, second and third sheets 111, 112 and 113 are thermally compressed, the first and second coupling parts 130a and 130b are inserted between the sheets 111, 112 and 113 and are bonded thereto while being compressed along with the first, second and third sheets 111, 112 and 113. In this case, in order to realize secure and stable bonding, a plurality of support holes 130 is formed in each of the first and second coupling parts 130a and 130b, and parts of the sheets 111, 112 and 113 are inserted into the support holes 131 when thermal bonding is performed. Furthermore, coupling holes 133a and 133b are formed in the respective exposed portions of the first and second coupling parts 130a and 130b.

[34] First and second insertion depressions 120a and 120b, into which the respective first and second coupling parts 130a and 130b are inserted, are formed in the authentication device 120. Coupling holes 121a and 121b are formed in the upper and lower surfaces of the device 120 and pass through the insertion depressions 120a and 120b. In this case, the number and size of coupling holes 121a and 121b correspond to those of the coupling holes 133a and 133b, which are formed in the respective first and second coupling parts 130a and 130b.

[35] As shown in Figs. 3 and 4, the authentication device 120 is coupled to the sheet body

110 in such a way that the authentication device 120 is mounted in the cut portion such that the exposed first and second coupling parts 130a and 130b are inserted into the respective first and second insertion depressions 120a and 120b, the coupling holes 133a and 133b are located to match the respective coupling holes 121a and 121b, and a plurality of coupling pins 125 is inserted into the coupling holes 133a, 121a, 133b and 121b to pass therethrough. In this case, it is preferred that rivets be used as the coupling pins 125, however, coupling means, such as screws or bolts/nuts, may alternatively be used.

The structure of the present embodiment is substantially the same as that of the previous embodiment, except for the structures of a coupling part and a coupling depression, which are used to couple the sheet body 110 with the authentication device in the present embodiment. Thus only descriptions of the coupling part and the coupling depression are made, but descriptions of the other components are omitted.

[38] Unlike the previous embodiment, the present embodiment employs a single coupling part 130 having an L shape, rather than employing two coupling parts. A plurality of support holes 131' is formed in a portion of the coupling part 130,' which is inserted into the sheet body 110, and thus safe and secure coupling with the sheet body 110 can be achieved. A plurality of coupling holes 133' is formed in an externally exposed portion of the coupling part 130.'

[39] An L-shaped insertion depression 120a,' into which the coupling part 130 is inserted, is formed in the authentication device 120. A plurality of coupling holes 121' is formed in the upper and lower surfaces of the authentication device 120 so as to pass through the insertion depression 120 a. The number and size of coupling holes 121' correspond to those of the coupling holes 133,' which are formed in the coupling part 130.'

[40] In the same manner as in the embodiment of FIG. 2, the authentication device 120 is coupled as shown in Figs. 3 and 4, and thus a detailed description thereof is omitted.
