İnternet kullanımının artması ve teknolojik gelişmelerle beraber insanlar her gün yüzlerce fotoğraf çekmektedir. Gün geçtikçe artan fotoğraflar telefon hafızasında fazlasıyla yer kaplamaktadır. Flash disk, bilgisayar ve telefonlarda bu fotoğrafların saklanması, kaybolma ve bozulma gibi durumlar nedeniyle çok güvenilir olmamaktadır. Bu durum telefon dışında yeni depolama alanları ihtiyacını ortaya çıkarmıştır. Bu noktada alternatif olarak bulut depolama sistemleri kullanılmaktadır. Bulut depolama alanları sisteme erişim ve saldırılara karşı güvenlik tedbirleri içermektedir fakat sisteme yüklenen resimler üzerinde doğrudan bir işlem yapmamaktadır. Bulut hesaplar bazen kötü niyetli kişiler tarafından ele geçirilmekte ve kişilerin fotoğrafları çalınabilmektedir. Bu durumu önlemek için depolama işleminden önce görüntü üzerinde şifreleme algoritmaları kullanan bir sistem önerilmiştir. Sistemde CodeIgniter (PHP Framework) altındaki çeşitli simetrik şifreleme algoritmaları karşılaştırılarak incelenmiş ve uygulama sonuçları sunulmuştur. Görüntülerin şifrelenerek farklı bir dosya uzantısı ile bulut depolama(AWS) ortamında ya da lokal ortamda saklanması sağlanmıştır. Bu çalışmada önerilen sistem ile görüntülerin tutuldukları ortamdan bağımsız olarak daha güvenli bir depolama imkanı sağlanması hedeflenmiştir.

SAFE STORAGE OF IMAGE FILES BY ENCRYPTING

Öz

With the increase in internet usage and technological developments, people take hundreds of photos every day. Photos increasing day by day take up a lot of space in the phone memory. Storing these photos in flash disk, computers and phones is not very reliable due to situations such as loss and deterioration. This situation has created the need for new storage areas other than the phone. At this point, cloud storage systems are used as an alternative. Cloud storage areas contain security measures against system access and attacks, but they do not directly work on the images uploaded to the system. Cloud accounts are sometimes hijacked by malicious people and photos of people can be stolen. In order to prevent this situation, a system that uses encryption algorithms on the images before storage has been proposed. Various symmetric encryption algorithms under CodeIgniter (PHP Framework) have been compared in the system and the application results are presented. Images are encrypted and stored in cloud storage (AWS) or local environment with a different file extension. With the system proposed in this study, it is aimed to provide a safer storage opportunity independent of the environment in which the images are stored.
