    • Pre-purchase and post-purchase item information provision methods and systems using an RFID technology and computer readable storage media storing programs for executing the methods are provided. A pre-purchase item information provision method for a radio frequency identification system according to the present invention includes transmitting, if a mobile reader is detected by a local server installed in a salesroom, a certificate containing information on a location of an object information service server and an authentication value to the mobile reader; transmitting, at the mobile reader, a query requesting an item ID to a tag attached to a target item; transmitting, at the tag, a item ID information generated by encrypting the item ID using the authentication value to the mobile reader; transmitting, at the mobile reader, the item ID information and the authentication value to the object information service server; and transmitting, at the object information service server, data retrieved in a database in correspondence to the item ID, the data being retrieved when the authentication value exists in the database. The item information provision method and system of the present invention can guarantee reliability of information on an item in the pre-purchase state and prevent the information from being eavesdropped in both the pre-purchase and post-purchase states. Also, the item information provision method and system can prevent the tag ID from being tracked, thereby protecting purchaser's privacy, preventing the tag from being forged, and improving computation efficiency.
    • 提供使用RFID技术的预购和购买后项目信息提供方法和系统以及存储用于执行方法的程序的计算机可读存储介质。 根据本发明的用于射频识别系统的预购项目信息提供方法包括如果由安装在销售室中的本地服务器检测到移动阅读器,则发送包含关于对象信息服务服务器的位置的信息的证书 以及对移动阅读器的认证值; 在移动阅读器处发送请求项目ID到附加到目标项目的标签的查询; 在所述标签处,通过使用所述认证值将所述项目ID加密到所述移动阅读器而生成的项目ID信息; 在所述移动阅读器处将所述物品ID信息和所述认证值发送到所述对象信息服务服务器; 并且在所述对象信息服务服务器处发送与所述项目ID相对应的在数据库中检索的数据,所述数据在所述认证值存在于所述数据库中时被检索。 本发明的物品信息提供方法和系统可以保证在购买前状态下的物品的信息的可靠性,并且防止信息在购买前和购买后状态被窃听。 此外,项目信息提供方法和系统可以防止标签ID被跟踪,从而保护购买者的隐私,防止标签被伪造,并提高计算效率。
