    • A method for generating documents having stored electrostatic pattern information provides security with respect to the authenticity of documents. A liquid medium including a plurality of electrostatic monopoles is applied to the surface of a document, which embeds a permanent electrostatic pattern in the document. The pattern is then readable by an electrostatic scanner. The monopoles may be associated with differing colors, including black and white, may be transparent or have a neutral color. The patterns may embed data, certificates or shapes. The monopoles may provide a watermark or visible image. The apparatus may be a pen or printer, and may include multiple selectable vessels containing ink and/or electrostatic liquid medium of one or both charge states. Visible features of the document can be compared with the detected pattern, or the pattern may be compared to a database or decrypted with a key.
    • 用于生成具有存储的静电图案信息的文档的方法提供了关于文档的真实性的安全性。 包含多个静电单极子的液体介质被施加到文件的表面,其在文档中嵌入永久静电图案。 该模式然后可由静电扫描仪读取。 单极子可能与不同的颜色相关联,包括黑色和白色,可能是透明的或具有中性色。 模式可以嵌入数据,证书或形状。 单极子可以提供水印或可见图像。 该装置可以是笔或打印机,并且可以包括含有一种或两种电荷状态的墨水和/或静电液体介质的多个可选容器。 可以将文档的可见特征与检测到的模式进行比较,或者将模式与数据库进行比较或用密钥解密。

    • A mechanism for storing authenticity information about a written or printed document. This authenticity information may be stored in a publicly-accessible database. When a document patterned with electronic ink is to be verified, the verifier examines the electronic ink under magnification. The verifier locates start and end pattern markers within the ink, and extracts the pattern from the ink. Once the pattern is obtained, the verifier performs a lookup of the pattern in the database. If the pattern is found, the verifier obtains information associated with the pattern from the database. The verifier may then use this information to verify the authenticity of the document.
    • 用于存储关于书面或印刷文件的真实性信息的机制。 该真实性信息可以存储在可公开访问的数据库中。 当用电子墨水图案化的文件要被验证时,验证者在放大下检查电子墨水。 验证者在墨水中定位开始和结束图案标记,并从墨水中提取图案。 一旦获得了模式,验证器就会对数据库中的模式进行查找。 如果找到该模式,则验证者从数据库获取与该模式相关联的信息。 然后,验证者可以使用该信息来验证文档的真实性。
