Abstract: The present invention relates to a device for managing website access blocking and permission, which includes, as an example, a catalog storage unit that stores a permitted catalog containing URL-permitted addresses of specific websites that permit access, and a blocking catalog containing URL blocking addresses of specific websites that blocks access; a URL input address processing unit that receives transmission of a URL input address inputted or processed on an Internet browser and separately processes the transmitted URL input address into a protocol, a host address, and an actual address; a permission/blocking determination unit equipped with a determination algorithm that loads the permitted catalog and blocking catalog stored in the catalog storage unit, receives the URL input address separately processed in the URL input address processing unit, and cross-compares the URL permitted address and URL blocking address on the catalog storage unit loaded for the URL input address to derive a result on wheth

Abstract: The present disclosure relates to a multi-party computation based digital signature apparatus, which includes at least: an individual private key generation unit generating an individual private key corresponding to a user; an individual private key pieces generation unit dividing the generated individual private key and generating pieces; an individual distribution key generation unit generating an individual distribution key corresponding to the user by using some of shared individual private key pieces of other users and some of the generated individual private key pieces; and a common public key generation unit generating a common public key by using the individual distribution keys of one or more other users and the individual distribution key of the user, and the individual private key of each user is broken to pieces, and then some of the broken individual private keys are shared for each user again to generate the individual distribution key.

Abstract: The present disclosure relates to a financial transaction system using individual distribution keys based on multi-party computation. The financial transaction system includes at least: a private key pieces generation unit dividing an individual private key corresponding to a user and generating private key pieces; an individual distribution key generation unit generating the individual distribution key corresponding to the user by using some of individual private key pieces shared with one or more other users and some of the plurality generated individual private key pieces; and a signature unit signing with the individual distribution key of the user, in which when a verification is performed by combining a signature value signed by the individual distribution key of the user and a signature value signed by individual distribution keys of one or more other users, the transaction is concluded between the users who sign.

Abstract: Disclosed are a portable skin condition measuring device, a skin condition analyzing method, and a program using the same. The skin condition analyzing method includes receiving input alternating current data and return alternating current data from the skin condition measuring device through a wireless communication, and comparing and analyzing the input alternating current data with the return alternating current data to provide skin condition information. The user identifies the skin condition of the desired skin area at the certain time point in real time. Accordingly, the user instantly checks and performs the appropriate prescription corresponding to the skin condition, and thus the user effectively maintains or improves the skin condition.

Abstract: An onscreen function execution method for a mobile terminal having a touchscreen is provided. The method allows for executing functions of an activated application by a tap on a specific area of the touchscreen. An onscreen function execution method of the present invention includes mapping active regions of the touchscreen to functions of at least one application, displaying an application screen in response to an application activation command and executing, if a tap is detected on one of the active regions, a function mapped to the application activation command. The active regions may include a function execution display region and the applications may comprise a camera application, a music player application, an idle mode screen application and the like. The method allows a user to execute functions of an activated application by tap on the touchscreen.
