Digital content player using chip card as storage medium and method of using digital content using same {DIGITAL CONTENT PLAYER USING CHIP CARD}

The present invention relates to a digital content player for recording and playing back digital content using a standard sized chip card as a storage medium and a method of using the digital content using the same.

Chip cards generally include cash cards, debit cards, prepaid cards, check cards, and the like. In general, MS type cards for recording cardholder-specific data in magnetic strips (areas) are generally used.

However, the MS type card has a tendency to be replaced by an IC chip card in recent years because of less information stored, and above all, a weak security structure.

The IC chip card is a card having a semiconductor chip equipped with an IC memory and a central processing unit. The IC chip card electrically contacts the surface of the chip card or communicates with an external interface terminal in a non-contact manner, compared with a conventional magnetic stripe (MS) card. It has a large storage capacity, and has a security function such as cryptographic processing and authentication of a connection object, a management function of data and information, etc. through a computation function through a CPU.

However, these IC chip cards can undermine the IC chip specifications according to international standards, despite the large memory capacity, arithmetic functions, and high level of security management functions compared to the existing MS cards. It is being used in financial transactions or in applications such as transportation cards because of concerns.

In addition, the standard IC chip of the IC chip card is programmed to be accessible only through a card reader provided by VAN for security reasons, and the available storage capacity is about 32KB, which is not widely used.

Recently, various IC chip card application service organizations have provided various application services. However, since a separate storage medium must be used to provide such a service, the chip card, which is a high value storage medium, is rarely used. There is a problem in that the manufacturing cost according to the purchase of a separate card, multiple cards must be provided, and the use of chip cards is not activated.

Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to be able to use a variety of applications using the chip card without damaging the IC chip according to the international standard mounted in the chip card without leaking personal information The present invention provides a digital content player using a chip card as a storage medium and a method of using the digital content using the same.

In addition, an object of the present invention is to provide a digital content player using a chip card as a storage medium, which can increase the utilization of the IC chip card by using digital content such as audio, video, and video such as UCC using the chip card as a storage medium; It is to provide a method of using digital content using the same.

In addition, an object of the present invention is to provide a digital content player having a chip card as a storage medium and a method for using the digital content using the chip card having an interface that can immediately use the chip card-related requirements necessary for using the chip card at the card use site. It is.
