Differential privacy (DP) provides a robust model to achieve guarantees for released information. We examine the protection potency of sanitized multi-dimensional frequency distributions via DP randomization mechanisms against homogeneity attack (HA). HA allows adversaries obtain exact values on sensitive attributes their targets without having identify them from data. propose measures disclosu...

In 1994 the City of Toronto Public Health Department conducted a needs assessment in the 235 child care centres (CCCs) in the former Toronto area. The purposes of the study were to construct a profile of Toronto's CCCs, to acquire a better understanding of these centres' operations and administration, and to assess their levels of compliance with current public health standards and regulatory r...

Earlier, Process of relevant pattern observation which is present in the database observed as a hurdle for database protection. Over the time, various approaches for hiding knowledge have emerged, mainly in the focus of Association rules and frequent item sets mining. This paper, have seen the problem in different view i.e., Knowledge hiding to the context where the data and extracted knowledge...

Sanitization is a protective and strategic approach to contain SARS-CoV2 dissemination. As there no feasible way deal with the new COVID-19 pandemic, sanitization has key role play. A modified method reduce spread of virus by constructing fogging room disinfectant base fluid mixture been examined. The nanometer-sized corona in micron-sized cough droplets can quickly reach inaccessible areas whe...

SQL Injection attacks target databases that are accessible through a web front-end, and take advantage of flaws in the input validation logic of Web components such as CGI scripts. SQL Injection attacks can be easily prevented by applying more secure authentication schemes in login phase itself. In this paper we are going to prevent SQLIA (SQL Injection Attacks) by using encryption in Stored Pr...

Sanitizable signatures allow a designated entity to modify some specific parts of a signed message and to produce a new signature of the resulting message without any interaction with the original signer. In this paper, we extend these sanitizable signatures to formally introduce trapdoor sanitizable signatures. In this concept, the power of sanitization is given to possibly several entities, f...

In addition to public health measures, including social distancing, masking, cleaning, surface disinfection, etc., ventilation and air filtration can be a key component of multi-pronged risk mitigation strategy against COVID-19 transmission indoors. Electrostatic precipitators (ESP) have already proved their high performance in fluid filtration, particularly industrial applications, control exh...

Livestock agriculture dominated by pig rearing is responsible for the production large volumes of wastes. Across the European Union there are over 151 million pigs that produce 300 million tonnes of slurry annually. Furthermore, intensive production linked to certain regions, leads to zones of nutrient excess where available land for land spreading is insufficient. However, even if the environm...
