In November 2018, the KISTI Tier-1 centre started a project to design, develop and deploy a disk-based custodial storage with error rate and reliability compatible with a tape-based storage. This project has been conducted in collaboration with KISTI and CERN; especially the initial design was laid out from the intensive discussion with CERN IT and ALICE. The system design of the disk-based custodial storage consisted of high density JBOD enclosures and erasure coding data protection, implemented in EOS, the open-source storage management developed at CERN. In order to balance the system reliability, data security and I/O performance, we investigated the possible SAS connections of JBOD enclosures to the front-end node managed by EOS and the technology constraints of interconnections in terms of throughput to accommodate large number of disks foreseen in the storage. This project will be completed and enter production before the start of LHC Run3 in 2021. In this paper we present the detailed description on the initial system design, the brief results of test equipment for the procurement, the deployment of the system, and the further plans for the project.

Verification Process

The proposed paper is discussed about the design, verification and analysis of a 32-bit Processing Unit.  The complete front-end design flow is processed using Xilinx Vivado System Design Suite software tools and target verification is done by using Artix 7 FPGA. Virtual I/O concept is used for the verification process. It will perform 32 different operations including parity generation and code conversions: Binary to Grey and Grey to Binary. It is a low power design implemented with Verilog HDL and power analysis is implementedwith clock frequencies ranging from 10MhZ to 100GhZ. With all these frequencies, power analysis is verified for different I/O standards LVCMOS12, LVCMOS25 and LVCMOS33.

Data perturbation is a data security technique that adds ‘noise’ to databases allowing individual record confidentiality. This technique allows users to ascertain key summary information about the data that is not distorted and does not lead to a security breach. Four bias types have been proposed which assess the effectiveness of such techniques. However, these biases only deal with simple aggregate concepts (averages, etc.) found in the database. To compete in today’s business environment, it is critical that organizations utilize data mining approaches to discover additional knowledge about themselves ‘hidden’ in their databases. Thus, database administrators are faced with competing objectives: protection of confidential data versus data disclosure for data mining applications. This paper empirically explores whether data protection provided by perturbation techniques adds a so-called data mining bias to the database. The results find initial support for the existence of this bias.

Sharing health and social care data is essential to the delivery of high quality health care as well as disease surveillance, public health, and for conducting research. However, these societal benefits may be constrained by privacy and data protection principles. Hence, societies are striving to find a balance between the two competing public interests. Whilst the spread of IT advancements in recent decades has increased the demand for an increased privacy and data protection in many ways health is a special case.UK, are adopting guidelines, codes of conduct and regulatory instruments aimed to implement privacy principles into practical settings and enhance public trust. Accordingly, in 2015, the UK National Data Guardian (NDG) requested to conduct a further review of data protection, referred to as Caldicott 3.  The scope of this review is to strengthen data security standards and confidentiality. It also proposes a consent system based on an “opt-out” model rather than on “opt-in.Across Europe as well as internationally the privacy-health data sharing balance is not fixed.  In Europe enactment of the new EU Data Protection Regulation in 2016 constitute a major breakthrough, which is likely to have a profound effect on European countries and beyond.  In Australia and across North America different ways are being sought to balance out these twin requirements of a modern society - to preserve privacy alongside affording high quality health care for an ageing population.  Whilst in the UK privacy legal framework remains complex and fragmented into different layers of legislation, which may negatively impact on both the rights to privacy and health the UK is at the forefront in the uptake of international and EU privacy and data protection principles. And, if the privacy regime were reorganised in a more comprehensive manner, it could be used as a sound implementation model for other countries.
