I have a private bucket with some csv files. I want to provide these files to the end user, but I do not want the end user to be logging into my S3 bucket console to download these files.
I can have a CloudFront distribution that allows access to these files only through the that distribution when I use Origin Access Identities (OAI). To fetch the files through cloudfront the user is expected to the know the full path of the file in S3.
In my case the user does not know the full path, or the name of the files. I am trying to find a way to render the csv files on S3 and provide them in some way to the user to download without having them go to the console. Ideally they would see a very basic folder structure that they can navigate and click on to download the files.
Does this require building a full web app? What is the easiest way?

i have a website similar to video hosting where i need to display upload videos and images and have the images be visible and also the videos if they are purchased, however their locations are saved in the database (MongoDB) and are displayed on the web-page and therefore show up in the network tab in the developer console.
this means that if you click on the link e.g. "https://s3.Region.amazonaws.com/bucket-name/key-name/folder/file-name.mp4" it will auto download, this only happens on chrome though but not Firefox where it just displays the object with no download option. i have tried to change the bucket policy, add encryption but either that causes the images that i want to display to become invisible as they are not publicly accessible or just has no effect and still allows for the video to be downloaded. is there any way for me to have the images and videos in the same bucket and have them both be visible under the right circumstances but block access to the bucket and prevent them from being downloaded by anyone but the bucket owner?
You cannot stop the downloads because the ability to show videos and images in a browser also means that the files are accessible via URL (that's how the browser fetches them).
One option is to use an Amazon S3 pre-signed URL, which is a time-limited URL that provides temporary access to a private object. The way it would work is:
Users authenticate to your back-end service
When a user requests access to one of the videos or images, your back-end checks that they are authorized to access the file
If so, your back-end generates an Amazon S3 pre-signed URL and includes it in the web page (eg <img src='...'>)
When the user's browser accesses that URL, Amazon S3 will verify that the URL is correct and the time-limit has not expired. If it's OK, then the file is provided.
Once the time limit expires, the URL will not work
This will not prevent a file being downloaded, but it will limit the time during which it can be done.
Alternate methods would involve serving content via streaming instead of via a file, but that is a much more complex topic. (For example, think about how Netflix streams content to users rather than waiting for them to download files.)
I am developing a LMS in Laravel and uploading all the video files to aws s3 bucket and can play them using video js player. But problem is, users can download the video files, which I want to stop. Can anybody suggest me is it possible or not? If possible, can anyone tell me how can I do that?
Objects in Amazon S3 are private by default.
However, if you wish students to make use of a file (eg a learning course video), you will need to grant access to the file. The best way to do this is by using Amazon S3 pre-signed URLs, which provide time-limited access to a private object.
For example, the flow would be:
A students logs into the LMS
A student requests access to a course
The LMS checks whether they are entitled to view the course (using your own business logic)
If they are permitted to use the course, the LMS generates a pre-signed URL using a few lines of code, and returns the link in a web page (eg via an <a> tag).
The student can access the content
Once the expiry duration has passed, the pre-signed URL no longer works
However, during the period where the student has access to the file, they can download it. This is because access has been granted to the object. This is necessary because the web browser needs access to the object.
The only way to avoid this would be to provide courseware on a 'streaming' basis, where there is a continuous connection between the frontend and backend. This is not likely to be how your LMS is designed.
In my app user upload images and I add watermark on it.Both are stored in different folder.
I want that original images only shown to those users who upload it and private to others.
In simple public for owner who upload it and private for rest .
I cant find any relevant bucket policy for it.
Is we can do like it?
If the data belong to the specific user, for me the rule of thumb is to keep the data private.
Never keep user data in s3 public, A single script can find the pattern of an object name and anyone can access the image data of any buddy.
If the images are some sort of assets then it's fine to make them public, but the rule of thumb "User data in S3 should be private"
Here is guideline to how to make data secure in S3 and also you should read user Data policy or declare user policy for your App.
I want that original images only shown to those users who upload it
and private to others.
The best option is presighned URL, generate a pre-signed URL for accessing to an object, you can set the time limit too, it means after that time, the URL not work and expired.
Here is the flow diagram.
You can read this slide.
amazon-s3-bucket-file-download-through-presigned-timebound-urls
save the object in such way that its name contain user metadata or the object contain metadata of user, save the file name in DB, during user request cross-check the metadata and generate presigned URL.
Is there a way to download the current site content, namely, the uploaded user images, from a web application on AWS? Everything I have found only gives access to previous code deployments, which do not include the user uploaded files.
I have tried the instructions here but it only seems to give access to the code as it was at the time of deployment.
Thank you for any help.
User uploaded images are usually stored in Amazon's S3 service, so go to your AWS dashboard and navigate to the S3 section, and you should find the files in a bucket there
Are you trying to download your own website ? Then you need to get not just code or user images; but also database containing data. You need to check the code where images are saved.. Are they on local EBS or EFS or S3 and correspondingly copy from there.
If you are trying to download some-one else website. Then surely you will not have access to database or code or other user images; but still you can download full website as seen to the public using many tools like WinHTTrack.
I have uploaded an image to S3 on Amazon Web Services. I just wanted to search for the image in the admin console of S3. I cannot find any search options there. Is there any other way?
Once in the console (e.g. in the bucket folder), you can just start typing the name of the object you are looking for. The list will refresh with the top file being the one you're searching for.
