    • PROBLEM TO BE SOLVED: To provide a system for encryption and decryption capable of achieving a high bit change rate and encryption strength while reducing computational complexity in performing encryption processing and decryption processing.
      SOLUTION: When an encryption processing section 110 receives plaintext data 10, the encryption processing section 110 encrypts the received plaintext data 10 in predetermined plaintext character units by referring to an encryption key table 210. This processing is repeated as needed to generate encrypted plain text data. On the other hand, when the decryption processing section 120 receives encrypted text data 20, the decryption processing section 120 decrypts the received encrypted text data in encrypted character units by referring to a decryption key table 220 to generate the plaintext data. In the decryption key table 220, the relation of an entry value representing the storage position of the data to a value stored in the entry is the same as the reversed relation in the encryption key table 210. For the data of a size the nth power of 2, encryption and the like of the data are achieved without using division.

    • 要解决的问题:提供一种能够实现高位变化率和加密强度的加密和解密系统,同时降低执行加密处理和解密处理时的计算复杂性。 解密:加密处理部分110接收明文数据10时,加密处理部分110通过参考加密密钥表210对预定明文字符单元中的接收明文数据10加密。根据需要重复该处理以生成加密 纯文本数据。 另一方面,当解密处理部分120接收到加密文本数据20时,解密处理部分120通过参照解密密钥表220解密加密字符单元中接收的加密文本数据,以生成明文数据。 在解密密钥表220中,表示数据的存储位置的条目值与存储在条目中的值的关系与加密密钥表210中的相反关系相同。对于第n次的大小的数据 2,数据的加密等不用划分就可以实现。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To prevent accidents caused by a mobile phone while driving a vehicle.
      SOLUTION: A navigator function of the mobile phone is used to recognize a moving speed of the mobile phone itself. If the moving speed reaches or exceeds a fixed speed, the mobile phone is automatically switched to a drive mode. If the moving speed becomes lower than the fixed speed later, the drive mode is canceled and it is reported by sound or vibration. Traffic signal waiting, traffic jamming and the like are considered for the timing of cancellation and the lapse of a fixed time may also be defined as conditions for joint use.

    • 要解决的问题:为了防止驾驶车辆时手机造成的意外。

      解决方案:手机的导航功能用于识别手机本身的移动速度。 如果移动速度达到或超过固定速度,手机将自动切换到驱动模式。 如果移动速度稍后低于固定速度,则驱动模式被取消,并且由声音或振动报告。 交通信号等待,交通干扰等被认为是取消的时间,并且固定时间的过去也可以被定义为联合使用的条件。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To solve the following problem: when a live-alone person becomes sick, gets injured, or is involved in a incident or an accident, a situation deteriorates, or it runs into death in some cases, with nobody noticing. SOLUTION: When an account system account of a person who opens an account previously contracting safety confirmation service is not accessed for a prescribed period or above, safety of the person who opens the account is inquired by a mail or telephone. When the safety cannot be confirmed thereby, a visit of a responsible person from a nearest branch, or a request to a security company, the police or the like is requested to confirm the safety. As the result of the safety confirmation, quick response is performed in the case that help is necessary. COPYRIGHT: (C)2006,JPO&NCIPI
    • 要解决的问题:解决以下问题:当一个独居的人生病,受伤或参与事件或事故时,情况恶化,或在某些情况下遇到死亡, 没人注意到

      解决方案:如果在规定期限内不能访问先前签约安全确认服务的客户的帐户系统帐户,则通过邮件或电话查询打开帐户的人员的安全。 当无法确认安全性时,要求负责人从最近的分支机构进行访问,或向安全公司,警方等进行请求,以确认安全。 作为安全确认的结果,在需要帮助的情况下执行快速响应。 版权所有(C)2006,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To prevent illegal transaction at an ATM by using a second password composed of a fixed number of digits of Hiragana (cursive form of Japanese syllabary), Katakana (Japanese square syllabary) and alphameric characters or more to a crime where forgery and theft of a card and illegal reading of a password are carried out simultaneously, so as to make it difficult to read the password illegally. SOLUTION: A transaction conclusion condition at the ATM is designated to be coincidence of the second password in addition to judgment of legitimacy and coincidence of the password. It depends on judgment of an account owner that whether the second password is to be adopted, and the second password can be registered from the ATM. The second password is composed of a fixed number of digits or more, and decided optionally by the account owner from Hiragana, Katakana and alphameric characters to be registered in a host system from the ATM.

    • 要解决的问题:为了防止使用由固定数量的平假名(草书形式的日语音节),片假名(日本方形音节)和更多的字母组成的第二密码在ATM处的非法交易 伪造,盗窃和非法阅读密码的犯罪行为同时进行,非法读取密码。 解决方案:除了判断合法性和密码重合之外,ATM的交易结算条件被指定为第二密码的一致性。 这取决于帐户所有者的判断是否采用第二个密码,并且可以从ATM注册第二个密码。 第二个密码由固定数量的数字或更多数字组成,并且由来自平假名,片假名的帐户所有者以及从主机系统中登记的字符字符来决定。 版权所有(C)2006,JPO&NCIPI
