知っておくべき EXIF の危険とその回避方法

EXIF データは Exchangeable Image File MetaData の略で、デジタル カメラで撮影した写真に埋め込まれています。 EXIF データには、特定のクリックの背後にある技術情報が含まれており、閲覧者は、写真家が写真をクリックするためにどのような技術的スキルと知識を使用したかを理解するのに役立ちます.

これには、カメラのレンズとモデル、露出設定、焦点距離、写真の通常の説明に関する情報が含まれます。このようなデータは情報と知識の両方の源であり、特に写真を研究している人にとっては、EXIF データは危険であり、所有者のプライバシーを脅かす可能性もあります.これは、すべての技術的要因に加えて、EXIF データには GPS 位置情報、所有者名、および個人情報も含まれているためです。このようなデータは、公開プラットフォームでリリースする必要がある場合に、写真の所有権と著作権を保持するために追加されます。

したがって、公開の画像共有プラットフォームまたはソーシャル メディア プロファイルで画像を公開する前に、EXIF データを編集または消去することが重要です。また、Photos Exif Editor のようなサードパーティ製ツールは、この仕事に最適です。下のボタンからダウンロードしてください-

EXIF メタデータがもたらす危険性

1.ジオタグ:

ジオタグは、写真が撮影された場所の座標です。ほとんどのデジタル カメラと携帯電話のカメラでは、設定で GPS が有効になっています。そのため、画像をクリックすると、撮影場所の場所が写真の EXIF メタデータに自動的に追加されます。この場所は、不正な ID、ログイン、およびアカウントのアドレスを偽造するために使用できます。

さらに、直接の場所からあなたの身元を突き止めることができ、これも悪用される可能性があります。 2007年、ジオタグの若者イラクの過激派がアメリカの航空機艦隊に迫撃砲攻撃を成功させ、4機のハイテクヘリコプターを破壊しました.このような些細なことが軍事作戦の歪曲を助長する可能性がある場合、個人のプライバシーと安全に多大な損害を与える可能性があります.

2.カメラのレンズとシリアル番号:

テクニックや、クリックした写真の背後にあるテクノロジーを明らかにしたくない人は、EXIF メタデータがすべての情報を保持していることに注意してください。したがって、写真を公開する前に、これらの詳細を編集することが常に賢明です。さらに、カメラのシリアル番号を使用して身元を追跡することもできます。

3.サムネイル

写真をクリックすると、永続的なサムネイルが形成されます。そのサムネイルには、追加の編集は反映されていません。 For example, if you’ve blurred a part of your image, the thumbnail would not reflect that blur, thus making your edits useless, as well as making you vulnerable to a privacy breach. This part of the thumbnail, where the applied censorship is rendered useless falls under an EXIF danger.

4. Date &Time

The EXIF data also records the date and the exact time when the picture was taken. This again notifies your activities to anyone who’ll go through that metadata. Giving away your place and time can sometimes be used against your interests by hackers.

5. Personal Information

In some scenarios, there are specific pictures that also adds personal information of the camera owner, including name and possibly any other contact details. This happens only if that particular person is using a device which has all these details integrated into the software. Many photographers do that on purpose to impose their copyright and also to promote their work on image-sharing platforms. However, it is essential that such data is edited or modified depending on the platform it’s being published. In case any picture with these details in Exif are released publicly, it can cause identity misuse or theft.

6. Deleting Properties is Not Reliable

A lot of users out there rely on Windows Properties to get rid of EXIF data of the pictures. In Windows, for removing Exif details, one can go to properties and delete them. However, relying on this measure doesn’t help out. The only thing that is removed by deleting Properties is your name and date of the image taken. Just deleting Properties won’t ensure deletion of Geotags, which means, your location would still be traceable via your pictures despite removing picture properties.

In such a scenario, using a tool like Photos Exif Editor for editing image metadata is the best choice.
