摘要： Digital signatures having an embedded view of signed data that lock the signed data but permit it to be repurposed are described. One of these digital signatures can be repurposed for signature by others, such as co-signers or counter-signers. Another of these digital signatures includes embedded information sufficient to recreate the embedded view using the signed data. A method for building a digital signature is also described that permits signing different parts of an electronic document.
摘要翻译： 描述具有锁定签名数据但允许其被重新利用的签名数据的嵌入视图的数字签名。 其中一个数字签名可以重新用于其他人签名，例如共同签名人或反签字人。 这些数字签名中的另一个包括足以使用签名数据重新创建嵌入视图的嵌入信息。 还描述了一种用于构建数字签名的方法，其允许签署电子文档的不同部分。
