    • Methods and systems that prevent completion of postdated financial transactions until the specified future date is provided. A portion of the information necessary to complete a financial transaction is encrypted utilizing an identity-based encryption (IBE) scheme. The encryption key used to encrypt the information is associated with the date on which the transaction is authorized to be completed. The encrypted information is provided to the payee. The issuing bank provides a daily decryption key that allows decryption of information encrypted using the key associated with the corresponding date. Thus, only when the maturity date of the transaction has arrived will the payee or depositing bank be able to obtain the decryption key that will decrypt the encrypted information necessary to complete the transaction. Since the encrypted information can not be decrypted until the date associated with the encryption key, the financial transaction can not be completed until such date.
    • 提供在指定的未来日期之前阻止完成后期金融交易的方法和系统。 使用基于身份的加密(IBE)方案来加密完成金融交易所需的一部分信息。 用于加密信息的加密密钥与交易被授权完成的日期相关联。 加密信息被提供给收款人。 开证行提供每日解密密钥,允许使用与相应日期相关联的密钥加密的信息进行解密。 因此,只有当交易的到期日到来时,收款人或存款银行才能获得将解密完成交易所必需的加密信息的解密密钥。 由于加密信息在与加密密钥相关的日期之前不能被解密,所以直到这样的日子才能完成金融交易。

    • A method of processing a check prior to submitting it for deposit in which the depositor's intent at the time of submitting the check is linked with an image of the check. The method includes receiving from the depositor intended amount information for the check, generating a first image of a front of the check, and generating an image of the intended amount. The method further includes generating a second image of the front of the check using the first image of the front of the check, wherein the second image of the front of the check includes the image of the intended amount and wherein the first image of the front of the check may be obtained from the second image of the front of the check. Finally, the method includes submitting at least the second image of the front of the check to a depository bank.

    • A voting method includes receiving identity-based information, vote data and a passphrase for a voter, encrypting the vote data using a symmetric key, generating second identity-based information for the voter, and generating an identity-based public key using at least the second identity-based information and a voting system parameter. The symmetric key is encrypted using the identity-based public key and an identity-based asymmetric encryption algorithm. The encrypted symmetric key may be decrypted using a private key corresponding to the identity-based public key and an identity-based asymmetric decryption algorithm, wherein the private key is generated from at least the identity-based public key and a secret master key. The voter is provided with information that includes at least the encrypted vote data and the encrypted symmetric key, and the system retains anonymous identity information, encrypted vote data and the encrypted symmetric key as a paper audit trail.
    • 投票方法包括接收基于身份的信息,投票数据和选民的密码,使用对称密钥加密投票数据,为投票者生成第二基于身份的信息,以及使用至少 第二个基于身份的信息和一个投票系统参数。 使用基于身份的公钥和基于身份的非对称加密算法对对称密钥进行加密。 可以使用对应于基于身份的公钥的私钥和基于身份的非对称解密算法来解密加密的对称密钥,其中从至少基于身份的公钥和秘密主密钥生成私钥。 向选民提供至少包括加密的投票数据和加密的对称密钥的信息,并且系统保留匿名身份信息,加密的投票数据和加密的对称密钥作为纸张审核跟踪。

    • A method and system for generating and printing an indicium, such as a postal indicium, on an object such as a mail piece. A digital image of other printed material, such as an address block, on the object is obtained, and the image is processed to abstract characterizing information descriptive aspects of the other printed material. The aspects can be measurements of word lengths, counts of outliers in images of characters, or descriptions of the shape of the other printed material. The characterizing information is combined with other information, such as postal information, and the combined information is then cryptographically authenticated with a digital signature or the like. An indicium representative of the authenticated information is then printed on the object. The object's relationship to the indicium can be verified by regenerating the characterizing information from the other printed material and comparing the regenerated characterizing information with characterizing information recovered from the indicium. Thus, copies of the indicium cannot easily be used, without detection, on other objects which do not include the other printed material.

    • A method, and deterministic random bit generator system operating in accordance with the method, for generating cryptographic keys and similar secret cryptographic inputs which are hard to guess. A seed is input from an entropy source; and an initial state is generated as a function of the seed. When a request to generate a cryptographic key is received a current state, where the current state is initially the initial state, is mixed to generate an out put string and a next state and the current state is set to the next state. The requested cryptographic key is generated from the string; and output. These steps can be repeated to generate successive output strings with assurance of forward and backward secrecy. An encryption system including such a generator is also disclosed.

    • A method and system for generating and printing an indicium, such as a postal indicium, on an object such as a mail piece. Other printed material, such as an address block, on the object is scanned, and the scanned image is processed to abstract characterizing information descriptive of the other printed material. Alternatively, the image to be processed can be obtained by filtering the original image wit a print/scan filter which simulates printing and scanning processes. The characterizing information can be text-based or image-based. Image-based characterizing information can be measurements of word lengths, counts of outliers in images of characters, or descriptions of the shape of the other printed material. The characterizing information is combined with other information, such as postal information and the combined information is then cryptographically authenticated with a digital signature or the like. An indicium representative of the authenticated information is then printed on the object. The object's relationship to the indicium can be verified by regenerating the characterizing information from the other printed material and comparing the regenerated characterizing information with characterizing information recovered from the indicium.
