数字代表着身份
企业需拥有大量的资讯可供随时调用，为什么这一点很重要呢？因为那样的话，亚马逊就知道你需要什么，能够给你提供你喜欢的书，而不是试图让你买你不喜欢的。那么，有什么不妥吗？
要是我正走在大街上，有人主动过来要卖给我什么东西的话，是不是很吓人？也许没那么吓人。人们试图卖给我东西并不是很吓人。就算他们不停地试图卖给我东西——显然他们已经老于此道—— 或者他们推销的方式令人不太舒服，也没什么吓人的。推销并不吓人，除非你是推销员。
要是我走在大街上，我的面孔被一个推销员的照相机拍照，这是不是很吓人？那也许令人讨厌，也可能是合法的。吓人吗？也许不。推销员对面孔背后的人又了解多少呢？
要是我走在大街上，我的面孔被一个推销员的照相机记录下来，而那照片可以与某银行或信用卡公司档案上我的正面相片自动比对，这是不是很吓人？这样的话，那个推销员就可能了解我大量的底细：我的姓名、我在哪家银行存款、我住在哪儿。
如果偷偷给我照相的不是推销员，是不是很吓人？
在日益强化、全球化、网络化的经济格局中，信息到处流通。迟早它会到达它的主人——或目前拥有它的任何人——能够随意处置它的地方。对方也许是遵守道德规范的——也许。
假如说我们从恐怖分子那里——更不用说从动作电影那里——学到了一招，那就是，工具也是武器。全球通用的信用卡和支持它们的数据库是去除商业摩擦的工具。换句话说，它们是以让各方最省事的方式从人们那里取钱的工具。
所以，如果他们是想卖给我东西，那没什么问题。如果对方是亚马逊，那也没问题。但如果都不是的话，那就有问题了。
我还没有提到身份盗窃，但这肯定是朝着那方向发展的。身份盗窃是指未经许可使用我的身份信息来行骗。我的信息流传得越广，可以找到它的地方就越多，发生盗窃的可能性就越大。与一个身份被盗的人相关的信息越多，身份盗窃案所造成的破坏就越大。
在我们的社会里，虽然没有人因为身份盗窃而丧命或被毁掉，身份盗窃仍是很令人担心的事情。还有比身份盗窃更糟糕的事；通用标识符也会导致那些更糟糕的事情。
无论通用身份的前景如何，我们尚不知道该如何应付这样一个世界：无论我身在何处，一切都可能与我有关联。一方面，这个世界给我们提供了无可置疑的种种方便；另一方面，我们又面对着所有这些强化组合的信息（如果是合理的强化组合该多好啊）所带来的种种危险。这种危险虽然模糊，但显然离我们很近。我们尚不知如何在两者之间保持平衡。
