Cloud computing is now a part of our day to day activities and we can’t deny the fact that all applications in smartphones are integrated with cloud. The data which is uploaded, stored or downloaded via the cloud needs to be secured during its static and dynamic status.
Watermarking is a technique of authenticity and helps to secure data which enhances cloud computing security. Have you ever thought how we use watermarking in our everyday activities and how it is available in our wallets or purses? Yes! Am talking about the currency notes which has the watermark on it.
Can this be digitized? Yes, it has already been digitized which we often see in our TV channels which are digital watermarked with logo: be it BBC or our local channels.
Consider introducing the traditional approach of watermarking techniques in cloud computing which has enabled to prevent breaches and alleviate security threats that has risen due to technology growth.
We all know that cloud business model supports on-demand, pay-for-use, and economies-of-scale IT services over the Internet. The virtualized data centers combine to form the internet cloud. To enhance the multiple data residence on the same cloud, the cloud needs to be designed to be secure and private because security breaches will lead to data being compromised. Cloud platforms are dynamically built through virtualization with provisioned hardware, software, networks, and data sets. The idea is to migrate desktop computing to a service-oriented platform using virtual server clusters at data centers.
We need to identify best practice process for cost effective security enhancements in cloud computing and watermarking has been analyzed to fit into this category . Increasing the public cloud usage with security enhanced clouds like using digital watermarking techniques helps in betterment of revenue for the cloud service providers and client.
Digital watermarking is a method that can be applied to protect documents, images, video, software, and relational databases.These techniques protect shared data objects and massively distributed software modules.
This combined with data coloring can prevent data objects from being damaged, stolen, altered, or deleted. Protecting data center must first secure cloud resources and uphold user privacy and data integrity.
The new approach could be more cost-effective than using the traditional encryption and firewalls to secure the clouds. This can be implemented to protect data-center access at a coarse-grained level and secure data access at a fine-grained file level. This can be interlinked with security as a service (SECaaS) and data protection as a service (DPaaS) and be widely used for personal, business, finance, and digital government data. It safeguards user authentication and tighten the data access-control in public clouds.
Public Watermarked clouds are an effective solution for security threats
It ensures confidentiality, integrity, and availability in a multi-tenant environment. Computing clouds with enhanced privacy controls demands ubiquity, efficiency, security, and trustworthiness.
Effective trust management, guaranteed security, user privacy, data integrity, mobility support, and copyright protection are crucial to the universal acceptance of cloud as a ubiquitous service. Effective less cost usage of public clouds leads to satisfied customers.
This blog would have thus enabled to identify the different security threats in cloud computing and identify best practice process for cost effective security enhancements in cloud computing which will in turn benefit the organization.
