Introduction

I. INTRODUCTION

In an age dominated by digital interactions and data-centric lifestyles, the demand for secure and accessible personal cloud solutions has become increasingly paramount. This project introduces a sophisticated Python-based personal cloud application, adeptly integrating the Flask web framework and cutting-edge cryptography techniques, with a specific emphasis on the Fernet algorithm. 

The central objective of this application is to establish a robust and secure file storage system within the personal cloud paradigm. Leveraging the Flask framework, the application provides a user-friendly interface for seamless file uploads and downloads. The cryptography component, employing the Fernet algorithm, plays a pivotal role in ensuring data confidentiality. Every file uploaded to the cloud undergoes automatic encryption, guaranteeing that sensitive information remains shielded from unauthorized access. Correspondingly, files are decrypted seamlessly for download, providing users with a streamlined and secure experience. 

  While the project prioritizes simplicity for instructional purposes, it serves as a foundational framework for more comprehensive and production-ready personal cloud environments. The discussion underscores the imperative need for additional security features, including robust user authentication mechanisms and granular access controls. Recognizing the evolving landscape of digital security, the project lays the groundwork for the development of a secure, user-centric, and feature-rich personal cloud, addressing the nuanced demands of modern data storage and accessibility. Through this initiative, the intersection of Flask, cryptography, and personal cloud technology emerges as a promising avenue for secure and tailored file management solutions. 

II. LITERATURE SURVEY 

In this research study, the author makes the argument that cloud computing's inability to protect user privacy and security Three key factors that clients lately took into consideration while signing up for cloud computing services are accessibility, keenness, and secrecy. Security lapses and instances of illegal access have been reported by several open and private cloud administrators. This document suggests that users encrypt their data before uploading it to a cloud storage platform such as Google Drive, Microsoft, Amazon, CloudSim, etc. The suggested cryptography computation was carried out on the advantage of Amazon S3 cloud space and is based on symmetric key cryptography demonstration. 

This research study proposes a novel parallel cryptography protocol that reduces the time complexity by using DNA atomic structure, one-time-pad plot, and DNA collection method. The Internet of Things (IoT) could be a collection of web-enabled objects that use stationary sensors to collect and correlate data. In today's IT environment, cloud computing and the Internet of Things (IoT) are the key advancements achieving significant impact. Due to their intelligence and resemblance to all computing devices, they tend to use them more frequently in sophisticated situations. The stage known as IoT cloud is created by combining these developments. There is a need for information security regarding the devices that these advancements connect, as a result of their widespread use. There are various concepts that been proposed for security of information.

In this paper, the creator proposes a ponder of half breed cryptography has been performed from 2015 to early 2019. Papers related to the issue were looked and almost 20 were considered on the premise of sifting in this consider. Of these, eight (8) are based on a userfriendly unthinkable study and 12 are indepth overviews.

The most point of this review paper is to supply increasingly data to the modern analysts, understudies in this field conjointly unpracticed in cryptography. The inquire about hole recognized are ignoring of client verification and disgraceful usage of the cross breed calculations.  

 In this paper, a multilevel cryptography based cloud computing security framework was suggested. The method used in the demonstration is a hybrid of symmetric and deviated key cryptography computations. In order to provide multilevel encryption and unscrambling at both the sender and collector sides, RSA and the Data Encryption Standard (DES) are used in this, increasing the cloud's security. In order to reduce security risks, this security demonstration provides clarity to cloud clients and cloud service providers. The suggested demonstration is implemented using the cloudsim cloud test system device and Java. In comparison to the current framework, this demonstration increases information security to an unprecedented degree and speeds up the upload and download of content records. 

 This paper presents Cross breed (RSA & AES) encryption calculation to defend information security in Cloud. Security being the foremost vital factor in cloud computing needs to be managed with extraordinary safety measures. This paper basically centers on the three key tasks-secure Transfer of information on cloud, secure download of information, appropriate utilization and sharing of the open, private and mystery keys included for encryption and decoding. The utilize of a single key for both encryption and unscrambling is exceptionally inclined to pernicious assaults. But in crossover calculation, this issue is unraveled by the utilize of three isolated keys each for encryption as well as decoding. Moreover, the key era method utilized in this paper is one of a kind in its possess way. This has made a difference in dodging any chances of rehashed or excess key. 

 In this paper, the creator proposes a framework, at whatever point the proprietor transfers a record, it is named with a set of properties that incorporates office, work profile, department, involvement which is called as get to structure. After this time interim, date and area too included. The client can decode and download the record in the event that the time interim, date area and traits matches with the proprietor set traits. Some time recently this, specialist will check whether client is authorized to get to any of the record. To realize more security record is part into numerous parts concurring to record estimate and stored on different hubs rather than being put away on a single hub. The framework has made a confirmable calculation, an authorized client get to and point by point approach. It moreover gives us the ensure of the rightness of the designated computer comes about. 

This term paper proposes that cloud computing is the most recent innovation within the field of disseminated computing. It gives different online and on-demand administrations for information capacity, arrange administrations, stage administrations, etc. Numerous organizations are apathetic approximately utilizing cloud administrations due to information security issues as the information dwells on the cloud administrations provider's servers. To address this issue, there have been a few approaches connected by different analysts around the world to fortify the security of the put away information on cloud computing. The Bi-directional DNA Encryption Calculation (BDEA) is one such information security method. Be that as it may, the existing procedure centers as it were on the ASCII character set, disregarding the non-English client of cloud computing. Hence, this proposed work centers on upgrading the BDEA to utilize with the Unicode characters.
