Alarm spreads among potential victims of domestic violence as cases multiply during the confinement required by COVID19, and authorities face the growing frustration of not knowing how to respond. The question of what to do begs the question of why the lockdown increases domestic violence. Loss of jobs, alcohol, and psychological stress are reasonable answers; but they are predictable and don't suggest new approaches for remedy. This essay considers an unsuspected if obvious trigger of violence at home. Boredom. It is a stressor that becomes intolerable as the pandemic lockdown continues. Since boredom is a volatile condition associated with the lack of engagement, and since boredom is resolved either creatively or violently, an evident program for primary prevention would be to provide disgruntled and potentially aggressive intimate partners with engaging activities. These activities address a responsibility of the State. When the State turns homes into places of involuntary confinement, it levies serious limitations on a range of human rights. Therefore, the State's obligation to address risks, including boredom, is a corollary to restricting freedom of movement. Perhaps the strategy to provide programs will face objections and skepticism. Why should potential perpetrators of violence be beneficiaries of pleasurable programs? And how can pleasure be a remedy when it carries a stigma of irresponsibility or sin? But a practical response to the spike in domestic violence will have to overcome this irrational stigma to become more strategic than moralizing (Sommer, 2014). We should address the spiral of aggression in ways that are effective, not reactive.
Nowadays, image steganography has an important role in hiding information in advanced applications, such as medical image communication, confidential communication and secret data storing, protection of data alteration, access control system for digital content distribution and media database systems. In these applications, one of the most important aspects is to hide information in a cover image whithout suffering any alteration. Currently, all existing approaches used to hide a secret message in a cover image produce some level of distortion in this image. Although these levels of distortion present acceptable PSNR values, this causes minimal visual degradation that can be detected by steganalysis techniques. In this work, we propose a steganographic method based on a genetic algorithm to improve the PSNR level reduction. To achieve this aim, the proposed algorithm requires a private key composed of two values. The first value serves as a seed to generate the random values required on the genetic algorithm, and the second value represents the sequence of bit locations of the secret medical image within the cover image. At least the seed must be shared by a secure communication channel. The results demonstrate that the proposed method exhibits higher capacity in terms of PNSR level compared with existing works.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
