Leiss is an early systematic treatment of protecting information in computerized systems—written when networked and distributed computing were becoming common enough that data security was emerging as a distinct technical discipline.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eRather than treating security as a collection of isolated tricks, Leiss approaches it as a fundamental problem of computer-system design. The book covers four major areas: the foundations and motivation of data security, \u003cstrong\u003estatistical database security, authorization and access-control mechanisms, and cryptosystems\u003c\/strong\u003e. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eThe statistical-database material is especially interesting historically. Researchers were already grappling with a problem that remains central to modern privacy engineering: even when users are prevented from directly viewing sensitive records, carefully constructed queries can sometimes reveal information indirectly. The mathematical examples in this volume examine ways information can be inferred from aggregate database responses.\u003c\/p\u003e\n\u003cp\u003ePublished only a few years after the landmark development of modern public-key cryptography, the book captures computer security at a formative point—before the commercial Internet, widespread personal computing, ransomware, cloud infrastructure, or modern cybersecurity terminology. Many of its core concerns nevertheless remain recognizable today: who should be allowed to access information, what they should be permitted to do with it, how databases can leak information indirectly, and how cryptography can protect stored and transmitted data.\u003c\/p\u003e\n\u003cp\u003eLeiss later continued working extensively in computer security, including authorization systems, digital signatures, inference control, authentication, viruses and worms, and protection of proprietary software. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAuthor:\u003c\/strong\u003e Ernst L.
