Privacy in the Genomic Era
Genome sequencing technology has advanced at a rapid pace and it is now
possible to generate highly-detailed genotypes inexpensively. The collection
and analysis of such data has the potential to support various applications,
including personalized medical services. While the benefits of the genomics
revolution are trumpeted by the biomedical community, the increased
availability of such data has major implications for personal privacy; notably
because the genome has certain essential features, which include (but are not
limited to) (i) an association with traits and certain diseases, (ii)
identification capability (e.g., forensics), and (iii) revelation of family
relationships. Moreover, direct-to-consumer DNA testing increases the
likelihood that genome data will be made available in less regulated
environments, such as the Internet and for-profit companies. The problem of
genome data privacy thus resides at the crossroads of computer science,
medicine, and public policy. While the computer scientists have addressed data
privacy for various data types, there has been less attention dedicated to
genomic data. Thus, the goal of this paper is to provide a systematization of
knowledge for the computer science community. In doing so, we address some of
the (sometimes erroneous) beliefs of this field and we report on a survey we
conducted about genome data privacy with biomedical specialists. Then, after
characterizing the genome privacy problem, we review the state-of-the-art
regarding privacy attacks on genomic data and strategies for mitigating such
attacks, as well as contextualizing these attacks from the perspective of
medicine and public policy. This paper concludes with an enumeration of the
challenges for genome data privacy and presents a framework to systematize the
analysis of threats and the design of countermeasures as the field moves
forward
A Security Pattern for Cloud service certification
Cloud computing is interesting from the economic, operational and even energy consumption perspectives but it still raises concerns regarding
the security, privacy, governance and compliance of the data and software services offered through it. However, the task of verifying security
properties in services running on cloud is not trivial. We notice the provision and security of a cloud service is sensitive. Because of the
potential interference between the features and behavior of all the inter-dependent services in all layers of the cloud stack (as well as dynamic
changes in them). Besides current cloud models do not include support for trust-focused communication between layers. We present a
mechanism to implement cloud service certification process based on the usage of Trusted Computing technology, by means of its Trusted Computing Platform (TPM) implementation of its architecture. Among many security security features it is a tamper proof resistance built in device and provides a root of trust to affix our certification mechanism. We present as a security pattern the approach for service certification based on the use TPM.Universidad de Málaga. Campus de Excelencia Internacional AndalucĂa Tec
Enhancement Data Security in Cloud Computing: Issues and Challenges
Cloud Computing can save an organization’s time and money but trusting the system is very much important because the real asset of any organization is the data which they share in the cloud to use the needed service by putting it directly in the relational database. No organization can transfer its data or information to a third party until a bridge of trust is built. This paper provides a concise and all roun小d analysis on data security and privacy protection issues associated with computing across all stages of data life cycle. It argues that, in contrast to the traditional solution where unauthorized third party can access organizational data illegally which raises a serious concern since data is scattered at different places all over the globe. The security concerns of users need to be addressed to make cloud environment safe and trustworthy. Every cloud provider solves this by encrypting data using encryption algorithm which is inadequate. The paper concludes by recommending that in addition to the traditional methods, the security of cloud computing can also be enhanced through authentication using thumb print, face, voice and image identification.
