Data privacy in knowledge discovery
No full textThis thesis addresses data privacy in various stages of extracting knowledge embedded in databases. Advances in computer networking and database technologies have enabled the collection and storage of vast quantities of data. Legal and ethical considerations might require measures to protect an individual's privacy in any use or release of the data. In this thesis, we address the problem of preserving privacy in the two following cases: (1) in distributed knowledge discovery; (2) in situations where the output of a data mining algorithm could itself breach privacy. We present results in two different models, namely secure multiparty computation (SMC) and differential privacy. The first part of the thesis presents privacy preserving protocols in the SMC model. Secure multiparty computation involves the collaborative computation of functions based on inputs from multiple parties. The privacy goal is to ensure that all parties receive only the final output without any party learning anything beyond what can be inferred from the output. Within this framework we address the problem of preserving privacy in the preprocessing and the data mining stages of knowledge discovery in databases. For the preprocessing stage, we present private protocols for the imputation of missing data in a dataset that is shared between two parties. For the data mining stage, we introduce the notion of arbitrarily partitioned data that generalizes both horizontally and vertically partitioned data. We present a privacy-preserving protocol for k-means clustering of arbitrarily partitioned data. We also develop a new simple k-clustering algorithm that was designed to be converted into a communication-efficient protocol for private clustering. The second part of the thesis deals with privacy in situations where the output of a data mining algorithm could itself breach privacy. In this setting, we present private inference control protocols in the SMC model for On-line Analytical Processing systems. In the differential privacymodel, the goal is to provide access to a statistical database while preserving the privacy of every individual in the database, irrespective of any auxiliary information that may be available to the database client. Under this privacy model, we present a practical privacy preserving decision tree classifier using random decision trees.Ph.D.Includes abstractVitaIncludes bibliographical referencesby Geetha Jagannatha
Tetranchyroderma hystrix Remane 1926
No full textTetranchyroderma hystrix Remane, 1926 Records from India. KERALA: Neendakara—Rajan & Nair (1979). Habitat. It has been recorded in well sorted sand with grain size ranging mostly from 295 to 592 µm Remarks. This species has been recorded by Rajan & Nair (1979) from Kerala in their ecological work, along with other gastrotrichs species and meiofauna. There is no drawing and other taxonomic data of this species provided by them or any other author from India. Consequently, we consider this species finding as a doubtful record that require more evidence to prove the presence of this species on the Indian coast.Published as part of Chatterjee, Tapas, Priyalakshmi, Geetha & Todaro, M.

An annotated checklist of the macrodasyidan Gastrotricha from India
No full textWe present a checklist of the macrodasyidan Gastrotricha fauna of India derived from original articles and comprehensive monographies regarding the Indian Fauna. Taxa and specimens described from India are discussed with special attention to their status, especially those species previously known from distant geographic areas. A total of 43 species have been recorded from 4 States and 2 Union territories. A careful taxonomic assessment indicated that many species are in need of re-description as the reported anatomical traits are not sufficient to grant a modern, robust identification. The situation is particularly poor for two species (Macrodasys indicus Govindankutty & Nair, 1969 and Paradasys lineatus Rao, 1980), which consequently, are considered here to be species inquirendae; moreover, the Indian records of Tetranchyroderma hystrix and T. massiliense reported from Kerala are doubtful and consequently the two species should not be included among the fauna of the Indian region until proper evidence is found. It is necessary to unravel the true identities of many Indian species through a comparison to topotypical material. We recommend that future comparisons between related species and conspecifics from different populations to include molecular sequence dat

Macrodasys lakshadweepensis Hummon 2008
No full textMacrodasys lakshadweepensis Hummon, 2008 = Macrodasys lakshadweepense Hummon, 2008 = Macrodasys indica Rao, 1991. Records from India. LAKSHASWEEP: Minicoy (Rao, 1991); GENERAL RECORD: Naidu & Rao (2004). Habitat. Marine intertidal; coarse and medium coralline sands, 5 cm below surface between low and high tide levels. Distribution. India (Arabian Sea). Remarks. Hummon (2008) named this species as Macrodasys lakshadweepense because the original name Macrodasys indica Rao, 1991 did not comply with the nomenclature rules. However, once corrected to M. indicus, it became a junior primary homonym of M. indicus Govindankutty & Nair, 1969. Finally, Hummon & Todaro (2010) corrected the species name from M. lakshadweepense to M. lakshadweepensis according to the genus gender.Published as part of Chatterjee, Tapas, Priyalakshmi, Geetha & Todaro, M.
