摘要： A method for detecting whether perforations are present on the edge of an image of a form, such as a check, includes obtaining a bitmap of the image, identifying a selected portion of the bitmap that corresponds to at least the edge and that includes a matrix of a plurality of rows and columns of brightness values, and selecting a particular one of the rows of brightness values. The method further includes performing a Fourier transform of the brightness values included in the particular selected row to generate a Fourier transform output, and determining whether a series of perforations is present based on the Fourier transform output. The method may also include steps wherein the brightness values are low pass filtered and wherein the values in the selected row are high pass filtered prior to the step of performing a Fourier transform.

摘要： An envelope used in voting by mail includes a signature area on which the signature is affixed and a concealing portion structured to cover the signature area thereby concealing the signature. The concealing portion includes a concealing layer that is preferably positioned on top of a protective layer. The protective layer is positioned between the signature area and the concealing layer when the concealing portion covers the signature area. The concealing layer is formed from a material that is normally opaque but becomes at least partially transparent when one or more chemicals are applied to the concealing layer. The protective layer protects the signature from the one or more chemicals since the protective layer is impermeable to the one or more chemicals.

摘要： Methods and systems for verification of indicia that do not require key management systems, and in which revocation of key pairs is easily performed without adding costs to the verification process are provided. Indicia are generated and authenticated utilizing an identity-based encryption (IBE) scheme. A key generating authority generates a private key for a PSD, distributes the private key securely to the PSD, and provides public information for use by a verification service when verifying cryptographic digital signatures generated with the private key. The corresponding public key is a string consisting of PSD information that is provided as part of the indicium. The verification service can verify the signature of each indicium by obtaining the public key string from the indicium, and utilizing the key generating authority's public information.

摘要： An electronic voting system includes a vote security device (VSD), a user interface for presenting a ballot to a voter, and an audit trail printer operatively coupled to the VSD. The printer prints an audit trail ballot only in response to verifying encrypted and/or digitally signed messages received from the VSD that indicates the voter's ballot selections. The printer is structured to allow the voter to view but not access the audit trail ballot. The voter is able to accept or reject the audit trail ballot using the user interface. If the ballot is rejected, the VSD causes the printer to print a rejection indicator on the ballot, and if the voter accepts the ballot, the VSD causes the printer to print an acceptance indicator on the ballot. A digitally signed record of the voter's ballot selections is generated and stored.

摘要： Methods and systems that provide privacy of signatures on envelopes containing ballots are provided. The envelope for returning ballots includes a flap with a window that aligns with a signature area on the envelope. The window appears opaque under normal lighting conditions, but appears transparent when illuminated with light having a predetermined wavelength. A movable signature stub is positioned on top of the signature area. The voter signs the back of the envelope on the signature stub, thereby imprinting a signature on the signature area by transferring a material from the signature stub to the signature area, and moves the signature stub. The flap of the envelope is then sealed, thereby covering the voter's signature in the signature area with the window of the envelope flap. To read the signature, light having the predetermined wavelength can be directed onto the window, thereby rendering the window transparent and the signature visible.

摘要： 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.
摘要翻译： 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。
