A STUDY ON CUSTOMER RELATIONSHIP MANAGEMENT IN CONSUMER MARKETS: GRANDIOSITY/ REALITY?

Relationship marketing (RM) was conceived as an approach to industrial and service markets, and was considered inappropriate in other marketing contexts. Recently, however, the domain of RM has been extended to incorporate innovative applications in mass consumer markets. Much has changed in a few short years. Recent applications of RM in consumer markets have been facilitated by developments in direct and database marketing within an increasingly competitive and fragmented marketplace. This paper presents a critical review of the history of RM in consumer markets, and incorporates important conceptual, practical, empirical and popular contributions. A number of critical issues which remain unresolved are identified in the paper. These form the basis of ten research propositions which are crucial to justifying and advancing the domain extension into consumer markets.relationship marketing, consumer marketing, consumer behavior

Some Efficient Solutions to Yao's Millionaire Problem

We present three simple and efficient protocol constructions to solve Yao's Millionaire Problem when the parties involved are non-colluding and semi-honest. The first construction uses a partially homomorphic Encryption Scheme and is a 4-round scheme using 2 encryptions, 2 homomorphic circuit evaluations (subtraction and XOR) and a single decryption. The second construction uses an untrusted third party and achieves a communication overhead linear in input bit-size with the help of an order preserving function.Moreover, the second construction does not require an apriori input bound and can work on inputs of different bit-sizes. The third construction does not use a third party and, even though, it has a quadratic communication overhead, it is a fairly simple construction.Comment: 17 page
